feat: Complete clean TV NFO processing implementation v2.0.0

- New EpisodeNFOManager class with video filename matching
- NFO files now match video filenames instead of S01E01.nfo format
- Clean TVSeriesProcessor with proper Sonarr API integration
- Proper date lookup: database -> Sonarr import history -> airdate fallback
- Updated manual scan endpoint to use new clean processor
- Removed all migration logic and nfo_migration_required sources

This is a complete rewrite of TV episode processing with focus on:
1. NFO filenames matching video files
2. Proper dateadded field population from Sonarr
3. Clean separation of concerns
4. Robust fallback logic
