fix: use StdRng for shuffling indices in fill_block function

- provider_configs: add id TEXT PK; migrate existing rows (provider_type becomes id)
- local_files_index: add provider_id column + index; scope all queries per instance
- ProviderConfigRow: add id field; add get_by_id to trait
- LocalIndex:🆕 add provider_id param; all SQL scoped by provider_id
- factory: thread provider_id through build_local_files_bundle
- AppState.local_index: Option<Arc<LocalIndex>> → HashMap<String, Arc<LocalIndex>>
- admin_providers: restructured routes (POST /admin/providers create, PUT/DELETE /{id}, POST /test)
- admin_providers: use row.id as registry key for jellyfin and local_files
- files.rescan: optional ?provider=<id> query param
- frontend: add id to ProviderConfig, update api/hooks, new multi-instance panel UX

+# Library Management — Design Spec
+
+**Date:** 2026-03-19
+**Status:** Approved
+
+## Context
+
+K-TV currently has ephemeral library browsing: metadata is always fetched live from providers (Jellyfin, local files) on demand, only accessible through the block editor filter UI. There is no persistent library, no cross-provider browsing, and no way to schedule directly from browsing media.
+
+This feature introduces an in-house library that syncs and stores media metadata from all providers into k-tv's own DB, then surfaces it through a first-class `/library` page where users can browse, filter, multi-select, and schedule media directly onto channels.
+
+---
+
+## Data Model
+
+### Migration `20260319000002_add_library_tables.sql`
+
+**`library_items` table**
+
+| Column | Type | Notes |
+|---|---|---|
+| `id` | TEXT PK | `"{provider_id}::{raw_item_id}"` — double-colon, matches existing registry prefix format |
+| `provider_id` | TEXT | `"jellyfin"`, `"local"`, etc. |
+| `external_id` | TEXT | Raw ID from provider (for re-fetching) |
+| `title` | TEXT | |
+| `content_type` | TEXT | `"movie"` \| `"episode"` \| `"short"` |
+| `duration_secs` | INTEGER | |
+| `series_name` | TEXT | NULL for movies |
+| `season_number` | INTEGER | NULL for movies |
+| `episode_number` | INTEGER | NULL for movies |
+| `year` | INTEGER | |
+| `genres` | TEXT | JSON array |
+| `tags` | TEXT | JSON array |
+| `collection_id` | TEXT | Provider-specific collection ID |
+| `collection_name` | TEXT | Human-readable name (synced from provider) |
+| `collection_type` | TEXT | e.g. `"movies"`, `"tvshows"` |
+| `thumbnail_url` | TEXT | Provider-served image URL; re-fetched on every sync |
+| `synced_at` | TEXT | ISO8601 timestamp |
+
+`thumbnail_url` is refreshed on every full sync. Frontend must handle broken image URLs gracefully (show a placeholder on load error) since URLs may break if provider URL or API key changes between syncs.
+
+**`library_sync_log` table**
+
+| Column | Type | Notes |
+|---|---|---|
+| `id` | INTEGER PK AUTOINCREMENT | |
+| `provider_id` | TEXT | |
+| `started_at` | TEXT | ISO8601 |
+| `finished_at` | TEXT | ISO8601, NULL while running |
+| `items_found` | INTEGER | |
+| `status` | TEXT | `"running"` \| `"done"` \| `"error"` |
+| `error_msg` | TEXT | NULL on success |
+
+### Migration `20260319000003_add_app_settings.sql`
+
+**`app_settings` table** — general-purpose key-value store for admin-configurable settings. Co-exists with the existing `transcode_settings` singleton table (that table is not modified). Seeded with: `INSERT OR IGNORE INTO app_settings(key, value) VALUES ('library_sync_interval_hours', '6')`.
+
+| Column | Type | Notes |
+|---|---|---|
+| `key` | TEXT PK | |
+| `value` | TEXT | Bare JSON scalar stored as text (e.g. `6`, not `"6"`) |
+
+`GET /admin/settings` returns parsed values: `{ "library_sync_interval_hours": 6 }` (number, not string). Backend parses with `serde_json::Value` on read; frontend receives typed JSON.
+
+---
+
+## Backend Architecture
+
+### Sync Engine
+
+**Layer placement:**
+- `LibraryItem`, `LibrarySyncResult`, `LibrarySyncAdapter` trait, and `ILibraryRepository` trait live in **`domain/src/library.rs`**
+- `FullSyncAdapter` (impl) and `SqliteLibraryRepository` (impl) live in **`infra/src/library/`**
+
+The `LibrarySyncAdapter` domain trait does **not** take a DB pool — DB writes are an infra concern handled entirely inside the impl:
+
+```rust
+// domain/src/library.rs
+#[async_trait]
+pub trait LibrarySyncAdapter: Send + Sync {
+    async fn sync_provider(
+        &self,
+        provider: &dyn IMediaProvider,
+        provider_id: &str,
+    ) -> LibrarySyncResult;
+}
+
+#[async_trait]
+pub trait ILibraryRepository: Send + Sync {
+    async fn search(&self, filter: LibrarySearchFilter) -> Vec<LibraryItem>;
+    async fn get_by_id(&self, id: &str) -> Option<LibraryItem>;
+    async fn list_collections(&self, provider_id: Option<&str>) -> Vec<LibraryCollection>;
+    async fn list_series(&self, provider_id: Option<&str>) -> Vec<String>;
+    async fn list_genres(&self, content_type: Option<ContentType>, provider_id: Option<&str>) -> Vec<String>;
+    async fn upsert_items(&self, provider_id: &str, items: Vec<LibraryItem>) -> DomainResult<()>;
+    async fn clear_provider(&self, provider_id: &str) -> DomainResult<()>;
+    async fn log_sync_start(&self, provider_id: &str) -> i64; // returns log row id
+    async fn log_sync_finish(&self, log_id: i64, result: &LibrarySyncResult);
+    async fn latest_sync_status(&self) -> Vec<LibrarySyncLogEntry>;
+    async fn is_sync_running(&self, provider_id: &str) -> bool;
+}
+```
+
+`FullSyncAdapter` in infra holds `Arc<dyn ILibraryRepository>` and calls repo methods internally — no DB pool leaks into domain.
+
+```
+infra/src/library/
+  mod.rs
+  full_sync.rs         -- FullSyncAdapter impl: calls list_collections for names/types,
+                          fetch_items(&MediaFilter::default()), repo.clear_provider + repo.upsert_items
+  repository.rs        -- SqliteLibraryRepository impl of ILibraryRepository
+  scheduler.rs         -- tokio interval task; 10s startup delay (hardcoded); reads interval from
+                          app_settings on each tick via AppSettingsRepository
+```
+
+**AppState** gains:
+```rust
+library_sync_adapter: Arc<dyn LibrarySyncAdapter>,
+library_repo: Arc<dyn ILibraryRepository>,
+```
+
+### Sync Concurrency Guard
+
+Before starting a sync for a provider, the scheduler and `POST /library/sync` handler both call `repo.is_sync_running(provider_id)`. If `true`, the scheduler skips that provider for this tick; the HTTP endpoint returns **409 Conflict** with body `{ "error": "sync already running for provider" }`. This prevents the truncate+insert race.
+
+### Admin Settings
+
+- `GET /admin/settings` — returns `app_settings` rows as parsed JSON object. Requires `is_admin = true` (`AdminUser` extractor).
+- `PUT /admin/settings` — partial update (only provided keys updated). Requires `is_admin = true`. Scheduler reads new value on next tick.
+
+### Library API Routes (all require authenticated user)
+
+| Endpoint | Notes |
+|---|---|
+| `GET /library/items?type=&series[]=&collection=&genre=&decade=&min_duration=&max_duration=&search=&provider=&offset=0&limit=50` | DB-backed; returns `{ items: LibraryItemResponse[], total: u32 }` |
+| `GET /library/items/:id` | Single item |
+| `GET /library/collections?provider=` | `{ id, name, collection_type }[]` from DB |
+| `GET /library/series?provider=` | `String[]` from DB |
+| `GET /library/genres?type=&provider=` | `String[]` from DB |
+| `GET /library/sync/status` | `LibrarySyncLogEntry[]` (latest per provider) |
+| `POST /library/sync` | Fires sync; 409 if already running; requires `is_admin = true` |
+| `GET /admin/settings` | `{ key: value }` map (parsed); requires `is_admin = true` |
+| `PUT /admin/settings` | Partial update; requires `is_admin = true` |
+
+**Existing library route API contract is unchanged** for all params except `offset`/`limit` (new). Frontend `use-library.ts` hooks continue working without modification.
+
+---
+
+## Frontend Architecture
+
+### New route: `/library`
+
+Added to main nav alongside Dashboard and TV.
+
+```
+app/(main)/library/
+  page.tsx                              -- layout, search/filter state, pagination state, multi-select state
+  components/
+    library-sidebar.tsx                 -- provider picker, type, genre chips, series picker, decade, duration range
+    library-grid.tsx                    -- paginated grid of LibraryItemCard
+    library-item-card.tsx               -- thumbnail (with broken-image fallback placeholder), title,
+                                           duration badge, content type, checkbox
+    schedule-from-library-dialog.tsx    -- modal (see flow below)
+    add-to-block-dialog.tsx             -- modal (see flow below)
+    sync-status-bar.tsx                 -- "Last synced 2h ago · Jellyfin" strip at top
+```
+
+### New hooks
+
+```
+hooks/use-library-search.ts     -- useLibrarySearch(filter, page): wraps GET /library/items with
+                                   offset/limit pagination. Query key: ["library", "search", filter, page].
+                                   onSuccess of useTriggerSync: invalidate ["library", "search"] and ["library", "sync"].
+hooks/use-library-sync.ts       -- useLibrarySyncStatus() → ["library", "sync"],
+                                   useTriggerSync() → POST /library/sync; on success invalidates
+                                   ["library", "search"] and ["library", "sync"]
+hooks/use-admin-settings.ts     -- useAdminSettings(), useUpdateAdminSettings()
+```
+
+Existing `use-library.ts` and its four hooks (`useCollections`, `useSeries`, `useGenres`, `useLibraryItems`) are **unchanged** — still used by `AlgorithmicFilterEditor` in the block editor.
+
+### Schedule From Library Flow
+
+1. User selects one or more items → floating action bar at bottom
+2. "Schedule on channel" → `ScheduleFromLibraryDialog` modal
+3. Modal fields (in order — time/days/strategy disabled until channel is selected):
+   - **Channel** picker (required; enables remaining fields once selected)
+   - **Days**: Mon–Sun checkboxes
+   - **Time**: `NaiveTime` input interpreted in the selected channel's timezone. Timezone label displayed inline (e.g. "20:00 Europe/Warsaw"). Disabled until channel is selected.
+   - **Duration**: For single item, defaults to `ceil(duration_secs / 60)` minutes shown in UI. For multi-item, user sets manually. Rounding to nearest minute shown explicitly (e.g. "1h 35m (rounded from 1h 34m 47s)").
+   - **Fill strategy**: Sequential (default for episodic) | Random | Best Fit
+4. Preview: *"3 blocks will be created on [Channel] — Mon/Wed/Fri at 20:00 [Europe/Warsaw], Sequential"*
+5. Confirm → `PUT /channels/:id` merging new `ProgrammingBlock` entries into `schedule_config.day_blocks`:
+   - Series / episodic: **Algorithmic** block with `series_names: [series]`
+   - Specific item(s): **Manual** block with those item IDs
+
+### Add To Block Flow
+
+1. User selects items → "Add to block" from action bar
+2. `AddToBlockDialog`:
+   - Pick channel
+   - Pick existing **manual** block: populated from `useChannel(id)` by collecting all blocks across all days with `content.type === "manual"`, **deduplicated by block `id`** (same block appearing Mon + Wed shown once)
+3. Confirm → appends item IDs to that block. Since the same block object (by `id`) may appear in multiple days in `schedule_config.day_blocks`, the PUT updates **all day entries that contain that block id** — the block is mutated wherever it appears, consistently.
+
+### Admin Settings UI
+
+Settings panel (cog icon in dashboard header, alongside existing transcode settings) gains a "Library sync" section:
+- Number input: "Sync interval (hours)"
+- "Sync now" button (visible to admin users only; calls `POST /library/sync`; disabled + shows spinner while running)
+- Status: "Last synced: [time] · [N] items" per provider from `GET /library/sync/status`
+
+---
+
+## Key Files Modified
+
+**Backend:**
+- `domain/src/lib.rs` — add `library` module
+- `domain/src/library.rs` — new: `LibraryItem`, `LibraryCollection`, `LibrarySyncResult`, `LibrarySyncAdapter` trait, `ILibraryRepository` trait, `LibrarySearchFilter`, `LibrarySyncLogEntry`
+- `infra/src/library/full_sync.rs` — `FullSyncAdapter` impl
+- `infra/src/library/repository.rs` — `SqliteLibraryRepository` impl
+- `infra/src/library/scheduler.rs` — tokio interval task, 10s startup delay
+- `api/src/routes/library.rs` — DB-backed handlers + sync/admin routes
+- `api/src/routes/mod.rs` — wire admin settings routes
+- `api/src/main.rs` — start sync scheduler task
+- `api/src/state.rs` — add `library_sync_adapter: Arc<dyn LibrarySyncAdapter>`, `library_repo: Arc<dyn ILibraryRepository>`
+- `migrations_sqlite/20260319000002_add_library_tables.sql`
+- `migrations_sqlite/20260319000003_add_app_settings.sql`
+
+**Frontend:**
+- `lib/types.ts` — add `LibraryItem`, `LibraryCollection`, `SyncLogEntry`, `AdminSettings`
+- `lib/api.ts` — add `api.library.items(filter, page)`, `api.library.syncStatus()`, `api.library.triggerSync()`, `api.admin.getSettings()`, `api.admin.updateSettings(partial)`
+- `app/(main)/layout.tsx` — add Library nav link
+- New files per structure above
+
+---
+
+## Verification
+
+1. **Sync**: `POST /library/sync` → 200. `GET /library/sync/status` shows `done` with item count. `library_items` rows in DB have `collection_name` and `thumbnail_url` populated.
+2. **Sync dedup**: Second `POST /library/sync` while first is running → 409 Conflict.
+3. **Library API pagination**: `GET /library/items?offset=0&limit=10` returns 10 items + `total`. `?offset=10&limit=10` returns next page.
+4. **Provider filter**: `GET /library/items?provider=jellyfin` returns only Jellyfin items.
+5. **Collections**: `GET /library/collections` returns `{ id, name, collection_type }` objects.
+6. **Admin guard**: `POST /library/sync` and `PUT /admin/settings` with non-admin user → 403.
+7. **Admin settings**: `PUT /admin/settings { "library_sync_interval_hours": 2 }` → `GET /admin/settings` returns `{ "library_sync_interval_hours": 2 }` (number). Scheduler uses new interval.
+8. **Library UI**: `/library` page loads, sidebar filters update grid, pagination controls work. `sync-status-bar` shows last sync time.
+9. **Broken thumbnail**: Item with a broken `thumbnail_url` shows fallback placeholder in `library-item-card`.
+10. **Multi-select action bar**: Select 3 items → action bar appears with "Schedule on channel" and "Add to block".
+11. **Schedule flow — time gating**: Time input is disabled until channel is selected; timezone shown next to input after channel selected.
+12. **Schedule flow — rounding**: Single-item selection shows rounded duration with note in dialog.
+13. **Schedule flow — confirm**: Series scheduled → Dashboard shows Algorithmic blocks on correct days with `series_names` filter.
+14. **Add to block — dedup**: Block appearing on Mon+Wed shown once in picker. Confirming updates both days.
+15. **Cache invalidation**: After `useTriggerSync()` resolves, `["library", "search"]` and `["library", "sync"]` query keys are invalidated, grid refreshes.
+16. **Block editor unchanged**: `AlgorithmicFilterEditor` works; `useLibraryItems` in `use-library.ts` unchanged.
+17. **Regression**: `cargo test` passes.
