feat(frontend): rebuild as Ambient/WebGL console with all pages + command palette

Ground-up rombak UI: hapus semua component/page lama, bangun ulang dengan
desain sistem Ambient (WebGL haze + drifting motes, signal-driven color)
di atas kontrak API/WS/type yang sudah ada.

- Design system: globals.css tokens + primitives (glass, button, badge,
  select, avatar, toast, chart SVG murni).
- Shell: nav rail, topbar (status WS + pill signal + theme), AppFrame.
- 8 halaman: dashboard, voice (orbital stage), media, messages (live feed +
  detail AI), moderation, analysis (search), recordings, + chatbot floating.
- Command palette (Cmd/Ctrl+K) untuk navigasi cepat.
- Server fetch di-page di-try/catch agar render graceful saat backend mati.

Verified: tsc clean, next build 8/8 halaman, semua route 200.
