📄️ Get the randomized property feed
Takes the EXACT same request body as POST /api/v1/crs/listings (search). Runs that same filter/search pipeline (unpaginated) to get the candidate listings, then returns a randomized, repeating stream of feed cards. Each card shows one random media item (image or video) drawn from the union of all properties' mediaTabs for that listing, plus the property name the media belongs to and the listing name. The order is fully random and a listing may repeat; every call returns a fresh feed. The 'size' rawParam controls the NUMBER OF CARDS returned (default 12, max 50) — not search pagination; 'page' is ignored.
