feat: implement federation post/connections backfill schedulers

schedule_actor_posts_fetch now spawns backfill_outbox in background,
fetching all pages of a remote outbox and persisting via accept_note.
schedule_connections_fetch follows AP collection next-links, resolves
profiles, and caches them in the DB. Both were no-ops ("deferred").

Add connections_repo field to ActivityPubService; wire both factories.

-- **Run tests before opening a PR.** At minimum: `make test-unit` (no database needed). For adapter changes: `make test-integration` with a live database. `make check` runs the full suite (fmt + clippy + tests).
+- **Run tests before opening a PR.** At minimum: `cargo test -p application` (no database needed). For adapter changes: `cargo test --workspace` with a live database.
 - **Keep the hexagonal boundary.** `domain` and `application` must not import any adapter crate. Use `&dyn Port` traits for all I/O.
 - **No ORM.** The project uses raw `sqlx`. Keep it that way.
 - **ActivityPub changes** — test against a live Mastodon instance if possible, or use the AP debug logs (`RUST_ENV=development`).
