Max 8d35e824ae Remove deprecated test files and refactor OAuth response handling
- Deleted obsolete test files for various OpenAPI components, including config_test.go, dsl_test.go, hello_test.go, oauth_test.go, oauth_token_test.go, and openapi_test.go, to streamline the codebase.
- Refactored OAuth response handling by integrating response methods from the response package, ensuring consistent error and success responses across OAuth endpoints.
- Enhanced error handling and response structure for improved clarity and maintainability, aligning with best practices for API responses.
