feat: festive Chinese red background and prize config unification

- Change all big screen backgrounds to pure Chinese red (#c41230)
- Remove vignette effect for consistent display on different screens
- Unify all prize data to match prizes.json configuration
- Add demo participants fallback when no data imported
- Fix particle visibility reset in startGalaxy()
