feat(career): bundle the AXA club venue pack (career stage 2) (#963)

The Velvet Room (50 stars) now ships in every build like the bar and
arena: 4 reactive crowd loops, 2 stingers, and a balcony flyover intro
rendered from the AXA Music Stage scene (110 spectators, state-scaled
stage washes over the venue's own neon). Audio files are dive-bar
placeholders until club-scale recordings land.

The installed/delete test now asserts bundled-fallback semantics:
with every venue bundled, deleting a downloaded pack reveals the
bundled copy instead of uninstalling.
