Refactor MQTT bridge handling in MyMesh to support RX and TX packet logging based on MQTT settings. Introduce mqtt_rx_enabled preference for default RX packet handling and update related logic in CommonCLI and MQTTBridge for improved configuration management. Enhance MQTTMessageBuilder to conditionally include SNR and RSSI for RX packets only.
