VOUT_MAX is the safety limit above which the UPS refuses to boot an
externally-powered Pi, not an output voltage setting. Also clarify

units: timeouts and watchdog values are CLI-scaled seconds,
AUTO_SHDN_TIME is minutes; SHDN_DELAY stays raw ticks.

Poll lifepo4wered-cli every 30s (configurable), publish all registers as

discovery. run.sh pulls broker credentials from the Supervisor mqtt
service (Mosquitto addon) with manual overrides in addon options.
