Feature: EMS-Konfiguration im Web-UI (v1.5.1)

- Modal zeigt EMS-Felder nur bei KATHREIN_WALLBOX (toggleEmsSection)
- openModal lädt ems_min_pv/timeout/target_hour/phases aus Gerätekonfig
- saveInverter speichert EMS-Parameter in inverters.json
- main.py übergibt EMS-Konfig aus inv_cfg an EmsController()
