Enhanced MQTT logging and client ID generation

- Enhanced logging for MQTT disconnections in MqttService.cs to include disconnection reasons and exception messages, with explicit error logging for exceptions.
- Implemented dynamic MQTT client ID generation using the machine name (TEAMS2HA_{Environment.MachineName}) and increased the keep-alive period from 30 to 60 seconds for improved connection stability.
- Updated the project file version in TEAMS2HA.csproj from 1.1.0.773 to 1.1.0.776, indicating a new release.
