Plex tracks produced no audio: local_queue_track had no "plex" arm so they were
enqueued as source="local", and there was no Plex resolve+play path.
- local_queue_track tags source="plex" and carries the string rating_key in
source_item_id_hint (the numeric queue id is a hashed/parsed form; the resolve
needs the original key); persisted in the session queue store.
- play_audible gains a "plex" arm -> play_plex_audible.
- play_plex_audible: qbz_plex::plex_resolve_track_media(base, token, rating_key)
-> player.play_data(bytes, id), mirroring the local-file seam. Bit-perfect:
play_data drives device init from the DECODED bytes; Plex metadata is
display-only. Covers album play, single track, and auto-advance.
