Refactor tests to improve response parsing and validation

- Introduced a new common module with response helper functions to streamline response parsing across tests.
- Updated role controller tests to assert success messages in responses for create, update, and delete operations.
- Enhanced role service tests to validate response structures and ensure proper error handling.
- Modified team controller and service tests to check for success messages and validate response data formats.
- Improved user controller and service tests to include success message assertions and error handling for invalid inputs.
- Ensured all tests utilize the new response parsing functions for consistency and maintainability.
