feat(web): add QueryErrorBoundary and use real map coordinates

Add global QueryErrorResetBoundary wrapping the app so TanStack Query
errors are caught with a retry UI instead of crashing. Enable
throwOnError in QueryClient defaults. Update ListingMap to use real
latitude/longitude from API when available, falling back to city-based
jitter for listings without coordinates.
