- Add missing TMDB async mock methods (_ensure_session, close)
to all TMDB mocks in test_nfo_workflow.py
- Refactor test_anime_add_nfo_isolation.py to mock get_nfo_factory()
instead of asserting on series_app.nfo_service directly
- Patch get_nfo_factory in test_background_loader_service.py
to align with factory-based NFOService creation
Fixes test failures caused by NFOService refactoring that introduced
explicit TMDB session lifecycle and NFO factory pattern.
- Add loading status fields to AnimeSeries model
- Create BackgroundLoaderService for async task processing
- Update POST /api/anime/add to return 202 Accepted immediately
- Add GET /api/anime/{key}/loading-status endpoint
- Integrate background loader with startup/shutdown lifecycle
- Create database migration script for loading status fields
- Add unit tests for BackgroundLoaderService (10 tests, all passing)
- Update AnimeSeriesService.create() to accept loading status fields
Architecture follows clean separation with no code duplication:
- BackgroundLoader orchestrates, doesn't reimplement
- Reuses existing AnimeService, NFOService, WebSocket patterns
- Database-backed status survives restarts
