/**
 * v1.4.41 W-ORG (org-audit rec #2) — DTOs for `/api/admin/backups`.
 *
 * Pre-v1.4.41 these interfaces lived inside the route handler at
 * `src/app/api/admin/backups/route.ts` and were imported directly from
 * the route module by `src/components/admin/backups-section.tsx`. That
 * was a textbook layer violation (component → route handler) and the
 * only one of its kind in the codebase. Hoisting the shapes here gives
 * both sides a route-handler-independent shared type home; the route
 * keeps owning the HTTP contract, the component keeps owning the UI.
