feat: Reale Jahresbelastung, must-have fixes, fitOut data coverage

Reale Jahresbelastung (Change 6):
- FitOutCostPanel zeigt Jahresmiete + amortisierte Ausbaukosten für alle fitOut-Werte
- FULL/PREMIUM: Ausbau CHF 0 (bezugsfertig), SHELL/BASIC: CRB/BKP-Richtwerte amortisiert über 5 J.
- Match-Card-Chip zeigt geschätzte Investition (orange wenn >100k)
- FitOutInvestment-Typ + calcFitOutInvestment() in fitOutUtils.ts
- BackendAIService + MockAIService mit generateFitOutAdvice (IAIService-Interface)

Must-have Kriterien (Nicht prüfbar Fix):
- ÖV-Anbindung: Minutengrenze aus Freitext extrahiert, gegen publicTransportMinutes geprüft
- Mindestfläche: m²-Wert aus Freitext extrahiert, gegen areaSqm geprüft
- Ausbaugrad: neues Keyword-Rule für FULL/PREMIUM

fitOut-Datenpflege:
- fitOut-Werte zu 32 fehlenden Properties ergänzt (Logistik=SHELL, Standard=BASIC, Modern=FULL)
- MAB-Werte (200/150/250 CHF/m²) zu 3 BASIC-Objekten hinzugefügt
