Adds a new s6 service (svc-foldingathome-mqtt) that polls the FAH 8 API
on port 7396 every 30 seconds and publishes 4 sensors to HA via MQTT
autodiscovery: Status, PPD, Work Unit Progress, and Credit estimate.
Requires the Mosquitto broker add-on; declared as mqtt:want so the
add-on remains functional without it.
