feat: Grundriss-Feature, Listenansicht mit Bildern, Gewerbe-Label, Image-Pool

- Grundriss (FloorPlanSection): PropertyUnit.floorPlanUrl?, Property.floorPlanUrl?;
  FloorPlanSection in MatchDetail + PropertyDetail; FloorPlanUrlSection in NewListing-Formular
- Listenansicht (MatchCardCompact): horizontales Layout mit 120px Bildstreifen,
  Score-Badge, Asset-Label-Overlay, alle 3 grünen Punkte, Anfrage-Button
- Light Industrial → "Gewerbe" überall (NeedInput, NeedCardPreview, CriteriaReviewPanel,
  newListingConstants, MyListings, propertyHelpers)
- "Zum Originalinserat"-Button nur bei Maison-Work-Objekten
- Image-Pool: propertyImageResolver mit sequentiellem Pool-Index (keine doppelten Bilder),
  nur Innenaufnahmen, rotate()-Trick für Sub-Pools
- Overlay-Labels (Objekttyp + Stadtteil) in LocationPreview + IntelligenceMatchCard
