BUG-003: HeatingRule auf heizungsrelevante Sensoren begrenzen

- matches(): nur climate oder sensor mit device_class in {temperature, humidity, occupancy, presence, heating}
- Tests: ergänzt für relevante und nicht-relevante Sensoren
- Verhindert falsche Empfehlungen bei Strom-/Tür-/Wetter-Sensoren
