Spreads TrackActionsButton across the second wave of surfaces.
PlaylistDetail track rows, LikedTab tracks, HistoryTab rows, and
Search results now expose the full 7-item menu. Each screen-level
Scaffold gains a SnackbarHost that collects TrackActionsViewModel
transient messages.
Search tracks section upgraded from text-only TextRow to TrackRow
with cover thumb + secondary line (artist or album) + kebab.
MiniPlayer + NowPlaying kebabs follow in a separate commit so the
shell-level snackbar plumbing can land independently.
