Subject: [PATCH] fix(docker): restore runtime NEXT_PUBLIC vars, add
 DEFAULT_LOCALE build arg
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Restore NEXT_PUBLIC_SUPABASE_URL + NEXT_PUBLIC_SUPABASE_PUBLIC_KEY at runtime
  (server code reads from process.env — needs these for SSR)
- Use external URL (API_EXTERNAL_URL) for both build and runtime
- Add NEXT_PUBLIC_DEFAULT_LOCALE=de as Dockerfile build arg so next-intl
  compiles with the correct default locale (was falling back to 'en')
- CACHE_BUST=3 to force full rebuild
