Backend:
- Load GOOGLE_CLIENT_ID/SECRET from DB at startup (env vars take priority)
- GET /api/settings/google-credentials → masked status (secret never returned)
- POST /api/settings/google-credentials → save to DB, hot-reload in memory
- /api/auth/google/url returns 503 with clear message when unconfigured
Frontend (ConfiguracoesView):
- OAuth credential inputs (Client ID + Client Secret with show/hide toggle)
- Shows configured status badge (ENV vs DB) and masked clientIdHint
- Instructions with redirect URI shown inline
