refactor: simplify NFO handling, remove legacy services

Browse Source 
- Drop nfo_factory, nfo_repair_service, nfo_service, series_manager_service
- Delete key_resolution_service, consolidate into folder_rename_service
- Remove bulk of NFO-related tests (coverage via integration tests)
- Streamline SeriesApp, background_loader, initialization services
- Add folder_rename_service to scheduler
