- useProperties: added usePropertyById, usePropertyMatches, usePropertySignals hooks
- propertyService.getProperties(), matchService.getMatchesForProperty(),
  futureSignalService.getSignalsForProperty() added
- PropertyFilterBar: asset type chips, availability select, sort select, search
- PropertyTable: sortable columns, row selection highlight, loading skeletons,
  empty/error states, Eye/Plus/Bookmark actions
- PropertyCard: decision-object card with header, primary, matchability,
  data quality and action zones; card states (selected, compareSelected,
  stale, low-confidence)
- PropertyDetailView: 7-tab detail panel (Übersicht, Hard Facts, Soft Factors,
  Matchability, Datenqualität, Quelle, Signale) with low-quality banner,
  missing field UX, data update CTA
- PropertyDetailSkeleton: loading state
- Properties page: two-panel layout (table + sliding detail panel)
