List line items on an order (with optional packable view)
Returns line items for a given order. Each item record includes product ID, SKU, quantity, unit price, discount, tax rate, and extended amount. Line items are not paginated; an order typically has 1-200 items.
Query param ?packable=true returns a SIMPLIFIED packable view used by the Edit Package
modal Items tab picker (NEW-GAP-EDIT-PACKAGE-ITEM-ADD-OUT-OF-ORDER-OR-OVER-QTY 2026-05-19).
The packable view aggregates by (order_id, product_id), filters kit parents and
returned lines, and includes ordered_qty, already_packed_qty, remaining_qty per row.
Without ?packable=true the standard order-item list is returned.
Requires orders:read scope.
