- Add fpdf2 dependency for dynamic test PDF generation
- Create tests/test_external_integrations.py with end-to-end pipeline tests:
- OpenAI: key validation, metadata extraction via chat completion
- Azure Document Intelligence: admin connectivity, full OCR on generated PDF
- S3: bucket access, upload/download/delete pipeline
- Dropbox: token refresh, upload/download/delete pipeline
- OneDrive: token refresh, upload/download/delete pipeline
- Authentik: OIDC discovery endpoint, credential consistency
- Full pipeline: Azure OCR → OpenAI metadata extraction
- Update tests/conftest.py to capture original env vars before test overrides
- Add has_real_env() helper and original_env fixture for credential detection
- All external tests use @pytest.mark.requires_external and skipif guards
- Test files are dynamically generated with unique content per run
- Uploaded test files are cleaned up in finally blocks
