List open invoices for multi-invoice payment modal
Returns open invoices (balance_due > 0, document_type IN (invoice, sales_order)) for a given account, sorted by due_date ASC then created_at ASC. The LIST is paged (limit/offset); meta.total_open_count and meta.total_open_amount report the TRUE full-account open totals (unbounded by limit) so callers never mistake a capped page sum for the account balance. Pass search (order-number substring or amount prefix) to locate a specific document past the first page; meta.filtered_count / filtered_amount then describe the search-matched subset. Requires payments:read scope.
