- Set relaxed rate limit (1000/minute) for dev/stage deployments
- Production keeps strict default (5/minute) for security
- Re-enable auth tests in CI (no longer excluded by marker)
- Update test docstrings to reflect rate limit configuration
- Add auth_intensive marker for tests that make many login requests
- Mark all tests in test_auth_api.py with auth_intensive
- Exclude auth_intensive tests from CI integration runs against deployed
environments (they trigger 429 rate limiting)
- Remove duplicate TestSecurityEdgeCases class definition
- Register auth_intensive, integration, large, slow markers in conftest.py
