🎮 Fix question selection, add score editing, media host-only playback

- Fix: select questions by questionIndex instead of points (fixes same-points categories)
- Fix: persist questionIndex in MongoDB schema for game state recovery
- Fix: update scores in UI on wrong answer
- Add: host can manually adjust team scores
- Add: audio/video plays only on host device
- Add: replay button for host after media ends
- Fix: answer media modal shown only to host
