This commit refactors `MQTTRepositoryImpl` to improve error handling and code formatting. It replaces generic `Exception` catches with specific MQTT, IO, and Serialization exceptions, ensuring better diagnostic logging and lifecycle management of the client loop.

Specific changes include:
- **Error Handling**: Updated `MQTTRepositoryImpl` to catch specific exceptions (`MQTTException`, `IOException`, `SerializationException`) instead of a generic `Exception` block.
- **Client Logic**:
    - Improved address parsing to dynamically select the default port (8883 for TLS, 1883 otherwise).
    - Added explicit handling for `CancellationException` in the MQTT client loop.
- **Code Style & Formatting**:
    - Applied consistent formatting across `MQTTRepositoryImpl.kt`, `MQTTRepositoryImplTest.kt`, and `MqttJsonPayload.kt`.
    - Removed the unused `DEFAULT_QOS` constant.
    - Simplified subscription logic and address parsing expressions for readability.
- **Testing**: Updated test files to match new formatting standards while maintaining coverage for address parsing and JSON payload serialization.
