Preserve main GNSS and volume behavior while porting verified TLS, receive fixes and full-handshake optimizations. Add MQTT connection diagnostics and route MQTT through banban.api.talkingq.com:1883. Include migration documentation and regression tools. Firmware builds and package checks passed; user confirmed new-board connectivity after switching the MQTT host to the domain.
