refactor(tv): integrate hierarchical monitoring and linter fixes

- Add SetTVShowMonitored/SetSeasonMonitored to monitoring service
- Add IsEffectivelyMonitored for Episode/Season
- Add GetEffectivelyMonitoredEpisodes
- Cascade unmonitoring through TV hierarchy
- Fix nullable types for TV entity IDs
- Simplify repositories with consistent patterns
- Add SeasonNumber to EpisodeFile for better queries
