Mitigate CI cache timeouts and wire venue door-staff dialogue

- Drop actions/cache@v4 from the checks job: the Gitea runner cannot reach
  GitHub's cache service (/twirp/...CacheService timeouts, ~2min retries);
  Godot import is fast enough without it. Add GODOT_SILENCE_ROOT_WARNING=1.
- Document the cache situation and re-enable path in docs/RELEASING.md
- VenueScenario.door_staff_line(context, rng): seeded-random venue lines
- GameManager logs id/ticket/wand-check, refusal, and prohibited-item lines
  from the venue scenario (Joke Shop flavor) during inspection/screening
- Test coverage: all Joke Shop contexts, unknown contexts, empty venues,
  deterministic seeded picks (54 tests pass)
