feat: Verwaltungszugang refactor — lease data, 3-tab detail, market signals

- Dashboard: remove QuickActionPanel, StrongMatchOverview, FutureSignalWidget,
  DataQualityWidget, header buttons, Marktchancen nav; KpiGrid → 4 cards
- Property domain: 9 new fields (leaseTerm, leaseStartDate/End, breakoutOption,
  currentTenant, importedFrom, importedAt, lastUpdatedAt)
- Mock data: annual CHF/m²/Jahr prices (×12), Swiss images, tenant/lease data
  for all 10 VERIFIED_PORTFOLIO properties; need budgets updated to annual
- PropertyTable: swap columns — add Aktueller Mieter, Mietlaufzeit,
  Breakoutoption, Breakoutoption Zeitpunkt; remove Verfügbarkeit, Konfidenz, Quelle
- PropertyDetailView: 3 tabs (Übersicht, Matchability, Marktsignale) with
  inline edit mode, NeedMatchCard list, PropertyMarketSignalsTab
- New: marketReport domain + mock data + service, NeedMatchCard,
  PropertyMarketSignalsTab with 4 sections + PDF button
- matchService: getNeedMatchesForProperty(propertyId, {minScore})
