refactor: GenericBadge + Provider-Isolation

Teil A — GenericBadge:
- Neue src/components/shared/GenericBadge.tsx mit zwei Varianten:
  transparent (${color}18 Hintergrund, farbiger Text, opt. Border)
  solid (gefüllte Farbe, weisser Text)
- Props: label, color, variant, showBorder, bold, icon, size, tooltip, ariaLabel
- 7 Badges auf GenericBadge refactored (Config-Objekt + 1-Zeiler):
  ReviewStatusBadge, ReviewPriorityBadge, ReviewEntityTypeBadge,
  AIOutputStatusBadge, AIErrorBadge, MatchStatusBadge, ShortlistStatusBadge
- Barrel-Export in src/components/shared/index.ts

Teil B — Provider-Isolation:
- src/mock-data/propertyStore.ts als neutrales Daten-Modul erstellt
- MockupPropertyProvider: importiert aus mock-data statt selbst zu definieren
- MockupUnitProvider: importiert aus mock-data statt aus MockupPropertyProvider
- matchSyncService: importiert aus mock-data statt aus MockupPropertyProvider
- Kein Provider importiert mehr einen anderen Provider
