feat: rare values + fortune wheel protocol + prize editor

Composers/parsers/events for rare values + wheel (open/spin/buy/data/result/
recent-wins) + admin (get/save prizes), headers 9300-9305 / 9400-9404.
fix: figure map uses split-aware loadGamedata (raw fetch broke on tier-manifest
gamedata, silently empty avatars).
