feat: implement market page with QueryProvider and dynamic listings
- wrap root layout with QueryProvider for React Query - replace market UnderConstruction placeholder with MarketClient and real data fetching - implement search, pagination, and sort via search params using getActiveListings - add necessary client components and queries - update dependencies (e.g., prisma, pkg-types)
