fix(player): show live track metadata, not the stale queue snapshot

The queue slice stores denormalized display fields captured at play-time, so the
player and queue panel kept showing pre-enrichment title/artist after a track's
metadata was updated — the library (RTKQ cache) and the player disagreed.

Add useResolvedQueueEntry: read through to the RTKQ Track cache and prefer its
fresh values, keeping the snapshot only as instant/offline fallback. Wire it into
PersistentPlayer (now-playing + cover) and QueuePanel (now-playing + up-next
rows), so enrichment updates reach the player through the same Track tags that
refresh the library.
