Migrate CIAM tests to use Key Vault-based GetCIAMUserAsync method

- Added GetCIAMUserAsync() method in LabUserHelper using Key Vault secrets
- Updated all 4 CIAM integration tests to use new method instead of direct API calls
- Verified all tests pass with Key Vault cached data
- Improves reliability by removing dependency on msidlab.com API calls
