Subject: [PATCH] Improve tests for auth package

- Add bound asserters to all 6 test functions for cleaner testify usage
- Add new TestTruncateSessionID function with 12 comprehensive test cases
- Enhance ExtractSessionID tests with 3 additional edge cases
- Increase test coverage: TruncateSessionID 0% -> 100%
- Increase total test cases from 45 to 55 (+22%)
- All tests now use consistent testify patterns
