docs(admin): clarify exam-corpus reset warning

app-dev built with --mode production was baking the PROD Supabase URL (.env)
into the bundle, so browser auth went cross-origin to supa.classroomcopilot.ai
and was CORS-blocked (and hit the wrong user store). Mirror the /__ccapi fix:
- Dockerfile: nginx /__supabase/ -> dev Supabase .94:8000 (+WS upgrade for realtime)
- supabaseClient.ts: resolve a leading-slash VITE_SUPABASE_URL against
  window.location.origin so supabase-js gets an absolute same-origin URL
- docker-compose.dev.yml: bake VITE_SUPABASE_URL=/__supabase (like VITE_API_BASE)
Browser now talks only to the app host (Tailscale or LAN), no CORS, dev .94 store.
