feat(frontend): Ambient/WebGL console revamp + lint/type cleanup

Ground-up rebuild of the GMW frontend as an Ambient Field console:
- WebGL ambient background (Three.js shader, drifting motes, reduced-motion aware)
- Glassmorphism dark cyber theme across all 8 routes
- SSR page + client view split with SWR fallback; realtime via WebSocket
- Command palette (Cmd+K), chatbot FAB, guild/channel pickers
- Chart primitives: donut, radial-gauge, area-activity, sparkline, equalizer

Cleanup (review pass):
- Remove stray Puppeteer nav-test/nav-debug scripts
- Replace non-null assertions with guards (dashboard/moderation)
- Drop unused useGuilds fetches in messages/voice views
- Type implicit-any `let` declarations across pages
- Add a11y roles/labels to SVG charts and audio, tidy imports
