- settings/src/integrations/schema.js: rename azure from 'Azure AD' to
'Azure Document Intelligence', swap fields to endpoint + api_key
- Add use_global_azure column (migration + model)
- global_settings_service: add azure to check_global_status and apply_global_overrides
- api/settings.py: expose use_global_azure in response/update; apply overrides
in test_azure_connection before credential check
- Settings.tsx: add 'Use credentials from main stack settings' toggle for
Azure OCR section (endpoint/key disabled when on, test button enabled when
global is configured); remove Users section (managed centrally via auth
service), clean up UserData interface, users query and mutations
