The 3-dot trigger and the modal-bottom-sheet menu it opens. 7 actions:
Play next, Add to queue, Like/Unlike, Add to playlist, Go to album,
Go to artist, Hide/Unhide. hideQueueActions: true suppresses the
first two for the Now Playing surface.
Sub-sheets (HideTrackSheet, AddToPlaylistSheet) land in subsequent
commits — this commit imports them speculatively, so CI between this
and the next two commits will fail. Resolved by Tasks 5 + 6.
