Capture the wand panel, escalation HUD and body-camera timeline

The three newest catalogue screens had AI mockups but no staged capture, so
compare and judge skipped them. capture_screenshots.gd now continues past the
night set:

- switches to The Joke Shop at 620 s (EVENING still has routine spawns), frames a
  guest, and retries the wand until it alerts; if nobody carries an alerting item
  it stages the documented keys false-alarm case.
- applies a formal warning (arms the body camera) then blocking, jumps to 760 s
  for night lighting, and captures the HUD at L3.
- closes the open incident and opens the body-camera timeline, which now shows
  the warning / body-camera / blocking rows.

Wired the refs for wand_screening, escalation_hud and body_camera_timeline, and
regenerated the escalation mockup as a third-person over-the-shoulder night shot
so the reference matches the game camera. Added Hud.clear_log() to drop
target-cycling noise from staged shots. README gallery lists the three captures.

Verification: headless 182/182, Python tooling 53/53, compare 9 good / 0 bad,
judge: wand match 0.90, timeline match 1.00, escalation review, 0 diff.
Version 0.3.3.
