	practice, so Controller.plant_name alone now decides all three (see
	server/brewpi.py).

	Delegates the actual construction to HeaterFactory/TempSensorFactory
	rather than importing HeaterHendi/TempSensor_max31865 directly, so
	those classes' hardware-only deps (spidev, pyserial) stay lazily
	imported - only actually needed when plant_name picks the real rig."""
