Delete ERP metadata
Removes specific metadata keys from the stored ERP metadata for a batch of entities of one type — customers (CUSTOMER), invoices (INVOICE), or invoice line items (INVOICE_LINE_ITEM). Only the keys you list are removed; other keys for the same entity and erpSource are left as-is, and the external id record itself is preserved. Scoped to the authenticated merchant. This clears only the value stored in Tabs — it does NOT blank the field in the ERP, because the sync skips empty/missing values, so a value already synced to the ERP stays put. Idempotent: removing a key that is already absent succeeds. One entityType per request.
