Extension: schedule OTA firmware flashes for the tent’s dark period – flashing reboots a node; auto-timing it to lights-off avoids disturbing a live photoperiod

WHAT: The Firmware tab does OTA ‘over the air, one build at a time, nothing flashed unless you queue it’. Flashes are queued for now, applied whenever. WHY: flashing a seat reboots it; doing that mid-photoperiod on a live grow briefly drops a sensor/actuator. The hub already knows each tent’s dark window (15:00-03:00 etc.). HOW: offer ‘apply this OTA at the next dark period for its tent’ as a queue option, so updates land when the lamp is off and the plant is least disturbed. Uses the photoperiod schedule already on the Light desk. Found live 8.2.0.
