refactor(fe): overhaul — split types, type-safe WS, remove dead deps/code

- Remove unused deps: gsap, @tanstack/react-query, three, r3f, drei, autoprefixer
- Split types from shared/api/client.ts into entities/{guild,voice,media,ui,recording,dashboard}
- Type-safe WebSocket handlers using WsEventMap — 0 'as' casts in App.tsx
- Replace gsap with framer-motion in AuthOverlay
- Remove dead code: useMascotSummary, gsapCardHover, live/components/index barrel
- Fix bare console calls → use createLogger from @bete/shared/logger
- Clean up unused imports and variables (aiVariant, etc.)
