Adds a heart action to the media notification implemented as a custom
control + customAction handler — NOT setRating, which is broken
upstream (audio_service #376: onSetRating never fires from a
notification tap) and previously blanked the Pixel Watch.
- res/drawable/ic_stat_favorite{,_border}.xml: white 24dp vector hearts
- audio_handler: favorite MediaControl.custom in _broadcastState
(icon/label toggle by LikeBridge state; kept out of
androidCompactActionIndices so compact/lock + Wear transport are
unchanged); customAction override (Future<dynamic>, matches base)
toggles the like then re-broadcasts; refreshFavoriteControl()
- player_provider: cascade refreshFavoriteControl into the likedIds
listener so liking from TrackRow/kebab/SSE flips the notification heart
Reliable on phone notification + lock screen; Wear/Auto display of a
non-transport custom action is platform-dependent (not a bug).
