Add unit tests for HassEntity and HassTopicBuilder

- Implemented comprehensive unit tests for the HassEntity class, covering entity configuration, publishing, and JSON generation.
- Created a mock for IMqttPublisher and ISettingsProvider to facilitate testing.
- Added tests for various scenarios including valid and invalid configurations, discovery topic generation, and MQTT publishing behavior.
- Developed unit tests for the HassTopicBuilder class, ensuring correct topic construction for discovery, state, command, and availability topics.
- Included edge case handling and performance tests for both classes.
