LikedAudioPinner downloads liked tracks' whole audio when "Keep liked
songs offline" is on: most recently liked first, one at a time, only
on an unmetered network while the server is reachable, and only while
the Liked budget has room for another track at CD bitrate, so it never
pushes out liked audio already on the phone. Tracks liked before this
ships are covered by the same pass. Any change (a like, an unlike, the
switch, the network) restarts the pass and cancels a download in flight.
Supporting changes:
- ConnectivityObserver.unmetered: the default network's NOT_METERED bit.
- Liked track ids are read newest first, and refreshIds stamps the
server's newest-first order into likedAt.
