useCostSummary

Base hook for the cost-summary reporting page (single-site mode). Owns the date-range / period UI state and the pure transform from a v2 `/auth/finance/cost-summary` response into headline metrics and time-series. Consumers wire their own fetch (RTK Query, TanStack Query, fixtures, ...) and pass the result through `query` - the hook never fetches itself. Multi-site mode is composed at the page level (T-13) by feeding a different response shape to the same view-model primitives; this base hook stays single-site to keep the input contract narrow.
