feat(android): TrackActions kebab on NowPlaying with hideQueueActions

NowPlaying gains the 7-item TrackActions menu in its bottom action
row alongside the View Queue button. hideQueueActions=true suppresses
Play next / Add to queue since the menu's track IS the playing one.
Go to album / artist pops NowPlaying first (it's a full-screen
overlay) before navigating, mirroring Flutter's shell-route hook.

Adds a thin Scaffold around the screen body so the TrackActions
transient messages have a SnackbarHost to surface in.

MiniPlayer kebab still deferred — needs shell-level snackbar
plumbing that lives outside this slice's scope.
