/**
 * TanStack Query-based hook for analysis page route `/site-finder/analysis/[cad]`.
 *
 * Unlike `useSiteAnalysis` (mutation-based, triggered on form submit), this hook
 * drives the analysis page where `cad` is a URL param — so we use `useQuery`
 * for automatic fetch + caching.
 *
 * Note: the 202 Accepted on-demand fetch flow is NOT handled here — the analysis
 * page assumes geometry is already available (the legacy page handles on-demand
 * fetching and can redirect to this route once done). For now, a 202 response
 * will surface as an error state.
