Adds circuits 2/3 (the configured ones on this Vitocal — Mixer One is
absent): supply temps 286/288, room temps 335/336 (radio room sensor
values as seen by the ECU), circuit pumps 402/403, operation states
1416/1417 (incl. frost-protection program state), DHW setpoint 396.
Closes the last cloud read dependencies (ViCare Vitodens entities are
unused clutter; everything actively referenced becomes local).
