Adds a commented, documented heating-device block to evcc.yaml: an
sgready-relay charger + heating loadpoint (surplus-threshold driven) plus
a heat-pump power meter (open3e DID 2488). Left INACTIVE so evcc doesn't
try to reach a relay that isn't wired yet. To activate: wire a Shelly to
the Vitocal SG-Ready terminals (143.1/143.4/143.5), enable SG in the
service menu, set host, uncomment. evcc drives boost/normal via SG-Ready;
the heat pump firmware owns the smart-grid logic.

Completes the evcc energy-manager config beyond meters:
- grid tariff: type custom reading the MQTT topic evcc/tariff/gridprice,
which an HA automation republishes from input_number.strompreis (HA
stays the single source of truth for the grid price).
- feedin: fixed 0.08 EUR/kWh (from the HA Energy dashboard).
- solar: forecast.solar plane derived from the HA forecast_solar config
(az 10 evcc / 60 deg tilt / 8.61 kWp at 49.49N, 11.76E).
- sponsor token left as a documented placeholder (not needed until a
commercial charger loadpoint exists).
