Refactor test data structure in gates.py and model_repository.py for improved clarity and consistency

- Updated test cases in test_gates.py to use dictionaries for prediction and response_time, associating values with timestamps.
- Modified test_predict_success in test_model_repository.py to create a DataFrame with named indices for better readability in assertions.
