- Fix the `dump_json` method in the `ModelView` class to call `model_dump_json` instead of `model_dump`, ensuring consistency in JSON serialization.
- Added a new test case in `TestListModelView` to verify the functionality of `dump_json` and check for correct IP address serialization.
- Added `.DS_Store` to `.gitignore` to prevent macOS system files from being tracked.
- Introduced optional development dependencies in `pyproject.toml`, including `pytest` and `responses`, to facilitate testing and development.
- Updated `uv.lock` with new package dependencies and versions for improved compatibility and functionality.
- Created new test files `conftest.py` and `test_view.py` to establish testing fixtures and implement unit tests for the `ModelView` class.
