Show actual local/missing track counts in Active Playlists

- Fetches current Jellyfin playlist track count
- Compares with Spotify playlist total to calculate missing tracks
- Shows: '25 local / 5 missing' instead of just track count
- Local = tracks currently in Jellyfin playlist
- Missing = Spotify tracks not yet in Jellyfin (need to be matched)
- Helps users see which playlists need track matching
