test: add comprehensive test suite for library system

- Add authentication middleware tests for JWT validation - Add library creation tests for admin authorization - Add library visibility control tests - Add user management and error handling tests - Add JSON validation and security tests - Add tests for both success and failure scenarios - Test edge cases like missing tokens, invalid data, unauthorized access - Use httptest for isolated API testing without needing running server - Include comprehensive test coverage for security and functionality Tests verify application security and multi-library system works correctly before deployment.
