test: Add comprehensive test coverage for security changes

- Add tests for token validation and security constraints
- Add tests for XSSI handling
- Add schema validation tests
- Ensure all edge cases are covered
- Remove unused isRemotePath function from utils

Builds on: brendan-kellam's positive feedback on mocked tests
