refactor: replace plant_name with per-component type keys in config

Browse Source 
PlantFactory.create() no longer takes plant_name; sim vs real is derived
from Heater.type. StirrerFactory is wired from Stirrer.type. HeaterFactory
registry key lowercased to "hendi" to match config. Controller.plant_name
removed from both config templates.

sim and real hardware are never actually mixed and matched in
practice, so Controller.plant_name alone now decides all three (see
server/brewpi.py).
"""Builds the heater/pot/sensor trio together as one consistent rig.
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."""
Each component's type comes from its own config section (Heater.type,
TempSensor.type) rather than a single plant_name key. The heater type
determines sim vs real: sim gets Pot (modelled plant) and TempSensorSim;
anything else gets PotReal and whatever TempSensor.type names.
Delegates to HeaterFactory/TempSensorFactory so hardware-only deps
(spidev, pyserial) stay lazily imported."""
