Greptile Summary

This PR fixes a test regression introduced by PR #24755, which incorrectly renamed the azure_api_key_header kwarg to AZURE_AI_API_KEY_header in 4 test call sites within test_user_api_key_auth.py. The actual function signatures for get_api_key() and _user_api_key_auth_builder() in litellm/proxy/auth/user_api_key_auth.py were never updated to match, causing the tests to fail with TypeError: got an unexpected keyword argument 'AZURE_AI_API_KEY_header'.

Key changes:

• Reverts 4 kwarg name changes in test_user_api_key_auth.py from AZURE_AI_API_KEY_header back to azure_api_key_header, aligning with the actual parameter names in the production code
• No test assertions or logic were modified — only the argument names at the call sites are corrected
• All 6 affected tests now pass (per the PR description)

Confidence Score: 5/5

• This PR is safe to merge — it is a minimal, targeted correction of incorrect kwarg names in tests, with no changes to production code or test assertions.
• The fix is straightforward and verifiable: the production function signatures (azure_api_key_header) are unchanged, and the test call sites are corrected to match. No assertions are weakened, no mocks are modified, and no production code is touched. The PR description includes passing test evidence.
• No files require special attention
