feat(plugin page): wire up screenshots + add compress script

- Update file paths to match provided .jpg captures (panel-overview, pair-qr,
  launch-option, entry-live)
- Flip HAS_SCREENSHOT for the 4 available ones; keep recording + session-form
  as placeholders for now (user will add in-game/phone photos later)
- entry-live.png → entry-live.jpg (smaller, still good quality at 1400px)
- All images compressed: Deck shots 1000px / q78, web shot 1400px / q78
- Add scripts/compress-screenshots.sh for re-compressing anytime
