Redesign dashboard zone card with live temps, AC status, and per-radiator state

Browse source 
Adds actual room-temperature capture for TRVs over MQTT and a background
Modbus poller for AC mode/fan/lock/room-temp, so the dashboard tile can show
real setpoint-vs-actual readings, an AC status block, and up to 3 radiator
icons per zone instead of just the setpoint.
