fix(music): revert to lavasrc 4.8.2, remove preferPartnerApi

- lavasrc 4.8.2 uses /tracks endpoint for playlists (4.8.3 /items
  returns 401 for new Spotify apps)
- Remove preferPartnerApi (anonymous token extraction broken on
  current Spotify web player)
- playlistLoadLimit stays at 10 (1000 tracks)
