agessaman 9d768a3cf7 Implement MQTT weather support in weather commands and configuration 
- Added new configuration options in `config.ini.example` for enabling and configuring MQTT weather sources.
- Updated `WxCommand` and `GlobalWxCommand` classes to retrieve weather data from custom MQTT topics, enhancing flexibility in weather data sources.
- Introduced error handling for MQTT data retrieval, ensuring robust responses for various error scenarios.
- Expanded translation strings in `en.json` to support MQTT-related messages, improving user feedback.

These changes enhance the application's capability to utilize MQTT for weather data, providing users with more options for weather information retrieval.
