feat: Add comprehensive tests for authentication module (#309)

* feat: add comprehensive tests for authentication module

- Add 33 unit tests covering all public functions in auth.rs
- Test IAMAuth struct creation and secret key validation
- Test check_claims_from_token with various credential types and scenarios
- Test session token extraction from headers and query parameters
- Test condition values generation for different user types
- Test query parameter parsing with edge cases
- Test Credentials helper methods (is_expired, is_temp, is_service_account)
- Ensure tests handle global state dependencies gracefully
- All tests pass successfully with 100% coverage of testable functions

* style: fix code formatting issues

* Add verification script for checking PR branch statuses and tests

* fix: resolve clippy uninlined format args warning
