 * Bulk upsert items masterdata.
 * Accepts a JSON array of items. Items are matched by `code` — existing items are updated, new ones are created.
 * Items missing `code` or `name` are silently skipped; validate your payload before sending.
 * Unit identifiers (`inventUnitId`, barcode `unit`) are normalised to lowercase and auto-created if they do not exist.
 * The server processes large arrays in internal batches of 5 000 items. Endpoint timeout is 5 minutes.
