Subject: [PATCH] Carry track duration through the queue pipeline
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ApiTrackLike/QueueItem had no duration field, so toQueueItem(s) always
dropped it and toTrack() hardcoded a new track's duration to 0, relying
entirely on the <audio> element's durationchange/loadedmetadata events
to fill it in once that track actually became current. Upcoming queue
rows never reach that point, so "A continuación" always showed a blank
duration even though the backend already returns it.

Add duration to both types, thread it through toQueueItems/toQueueItem/
trackFromQueueItem, and seed toTrack() from it. The real-time audio
sync still overwrites it once a track actually plays, so this only
fills the gap for tracks that haven't played yet.

Also map MixItemApplicationResponse's durationSeconds through
mixItemTrack, since mixes use a differently-named field.
