Comprehensive fallback enhancement: Accept any TMDB type + Radarr NFO premiered dates

- TMDB now accepts ANY release type (1-6+) for maximum coverage
- Added Radarr NFO <premiered> date extraction as additional fallback
- For rename-first movies: Import → Any TMDB → Radarr NFO → File dates
- Much more aggressive about using ANY reasonable date over bad file dates
- Covers edge cases where TMDB has unusual release types

Version bumped to 0.2.20
