Move auto_scheduler, library_sync, broadcast_poller, webhook_consumer from presentation/background/ into crates/worker/src/jobs/. Presentation is now a pure HTTP server.
Axum binary that wires all clean-arch crates together: - AppState holds pre-built Deps structs (auth, channels, schedule, library, etc.) - JWT extractors (CurrentUser, AdminUser, OptionalCurrentUser) - Handlers delegate to application use cases, map to api-types DTOs - Routes: auth, channels, schedule, library, admin, providers, config, iptv - Background: auto-scheduler, broadcast poller, webhook consumer, library sync - Factory builds everything from Config + DbPool - SimpleProviderRegistry impl of IProviderRegistry trait - NoopMediaProvider fallback
