perf(web): optimize bundle size — dynamic import Mapbox GL and code split Recharts

- Dynamic import ListingMap with next/dynamic (ssr: false) in /listings/[id] and /search pages
- Extract Recharts into lazy-loaded DistrictBarChart and PriceTrendChart components
- /listings/[id] first-load JS: 618KB → 149KB (-76%)
- /search first-load JS: 619KB → 150KB (-76%)
- Both pages now well under 300KB target
