- Introduced a new test file `test_models.py` to implement unit tests for various device models in the `device_registry`.
- Added parameterized tests to validate the parsing of device configurations against expected JSON outputs and to ensure required sections are present in the parsed models.
- Enhanced test coverage for multiple device types including Mikrotik, Keenetic, Qtech, Huawei, Eltex, and Quasar.
