The canonical tracklist carried the old track name "Aria Sans Serif" and, worse,
a `file` pointing at live/collab/raph/aria_sans_serif.tidal — a path that no
longer exists. The track was renamed to Mafia Sans Serif in the score long ago
(real file: mafia_sans_serif.tidal); only the published metadata lagged. Since
the track identity in the armada catalog pipeline IS its .tidal path, the
dangling ref meant the catalog keyed this track on a non-existent score.
Fixed both the display name and the file ref to the real score. This is the
canonical root: the armada catalog regenerates from here (tide.py build).
