zarzet 5259c86365 feat(player): add Mornye media notification controls
Sync notification favorites with Library, add Mornye transport icons and an output action on legacy Android, and expose the iOS favorite command. Preserve playback position when controls refresh.

Vendor audio_service 0.18.19 with a small Android patch for custom notification actions. Modern Android keeps its system output switcher and transport layout.
