Every company's documents for the admin management page, paginated. A document archived by any company is left out (it lists under the archived documents instead). Sortable by id, name, type, companyName, createdBy and updatedAt; the filter JSON matches name and companyName as substrings, id and companyId exactly, and type against comma-separated document type ids. fileUrl is a read-only link valid for an hour; originalFileUrl is the storage key. Answers the paginated { data, metadata: { pagination } } envelope (1-based pagination.page). Migrated from the legacy api-service GET /v3/admin/company-documents.
