Feature: Eigenversorgungs-Ersparnis in Perioden-Karten (v1.8.2)

Browse Source 
- bat_discharge_total + bat_charge_total werden jetzt als Perioden-Starts getrackt
- savings_kwh = Batterie-Entladung der Periode (→ Haus + Auto)
- savings_eur = savings_kwh × effektiver Importpreis (Festpreis oder Börsendurchschnitt)
- Neue Karte "Eigenversorgung" (lila) neben Netzbezug/Einspeisung
- Preis-Refaktor: eff_price für Import, Export, Ersparnis aus einer Berechnung
