fix(android): LikedTab tracks tap to play

Track rows in the Liked tab had .clickable(enabled = false) with a
"Phase 9" deferral comment, silently breaking the most common
interaction on the list. Mirror the HistoryTab pattern: inject
PlayerController, expose playTracks(list, index), and route taps
through to PlayerController.setQueue with source = "liked". Row
clickability is gated on streamUrl so rows that can't be played
stay inert.
