Fix null boolean error and playlist count showing 0 after restart

- Added all required boolean fields to MediaSources (IsRemote, IsInfiniteStream, RequiresOpening, etc)
- UpdateSpotifyPlaylistCounts now loads from file cache if Redis is empty
- This fixes 'type Null is not a subtype of type bool' error in Finamp
- Playlist counts now show correctly even after container restart
