 * One-time backfill to the newer catalog model.
 *
 * - Ensures `catalogs/*` has `catalogType`, `catalogItems`, and `metadata` envelope.
 * - Migrates legacy top-level `status`, `createdAt`, `updatedAt` into `metadata.*`.
 * - Ensures native item records under `catalogData-{catalogId}-items/*` have `metadata.createdAt` and `metadata.lastUpdate`.
 * - Converts legacy `catalogDefinitions/*` native `storage` into `catalogItems.providerType: internal` (best-effort).
