fix: close spec gaps — delete InquiryStatusBadge, extend match reasons, full field keys

- Delete InquiryStatusBadge.tsx (dead code after Part A read/unread migration)
- AdditionalPropertyMatch: add reasons[] + topUncertainty from positiveFactors/tradeoffs
- AdditionalMatchCard: render green reasons and amber uncertainty below match score
- ReportObjectFieldKey: add breakoutOptionDate, roomHeight, floorLoad, deliveryAccess,
  goodsLift, passengerLift, internet, microLocation, competitionEnvironment,
  infrastructure, marketSignals, negotiationHints, missingData (now 45 keys)
- ReportObjectFieldSelector: regroup into 5 spec-aligned groups (Basisdaten,
  Miet-/Vertragsdaten, Technische Hard Facts, Soft Factors, Marktinformationen)
- LatentInquiryReportPreview: add labels for all new field keys
