List Meta product catalogs

Lists the Meta product catalogs reachable from an ad account (owned + agency-shared catalogs of the ad account's business), for Advantage+ catalog ads (goal: catalog_sales on POST /v1/ads/create — e.g. vehicle inventory catalogs). Read-only; uses scopes customers already granted (no reconnect needed). Catalog contents (items, feeds) are managed in Meta Commerce Manager, not through this API.
