player bar: the album line survives library plays, and lands with the title

Two halves of one defect family. The meta line preferred the queue item's
artist/album fields as a PAIR whenever either existed — but a library play
(playAlbum) writes only `artist`, with the record's name living inside
`sub` ("artist — album"), so `album: null` was taken at face value and
every library album lost its name from the bar (and the morning comment
claiming local rows carry neither field was simply wrong). Each half now
falls back to the `sub` split on its own, here and in the rail's byline —
which also restores the album for continuation items whose `sub` is a
bare artist.

And the line no longer trickles in: the buffering branch used to render
the artist alone, so the album flashed in a beat after the title when
playback started. The status gate is replaced by a REAL distinction — a
resolver-phase track has no `path` (playQueueIndex always writes one), so
"finding best source…" still shows as a bare label, and the moment a real
queue item owns the transport the full clickable line renders, buffering
or not. Measured: the first frame carrying the new title already carries
artist · album; no artist-only frame exists.
