feat: Fork octo-fiestarr as allstarr with Jellyfin proxy improvements

Major changes:
- Rename project from octo-fiesta to allstarr
- Add Jellyfin proxy support alongside Subsonic/Navidrome
- Implement fuzzy search with relevance scoring and Levenshtein distance
- Add POST body logging for debugging playback progress issues
- Separate local and external artists in search results
- Add +5 score boost for external results to prioritize larger catalog(probably gonna reverse it)
- Create FuzzyMatcher utility for intelligent search result scoring
- Add ConvertPlaylistToJellyfinItem method for playlist support
- Rename keys folder to apis and update gitignore
- Filter search results by relevance score (>= 40)
- Add Redis caching support with configurable settings
- Update environment configuration with backend selection
- Improve external provider integration (SquidWTF, Deezer, Qobuz)
- Add tests for all services
