<!--
  "سفارش مشتریان" — the sales expert's referred customers' orders.

  Ported from legacy henza_pwa/src/views/user/src/components/ChildOrders.vue,
  restyled into this app's design language (PageBar + SearchInput + cards, as
  OrdersView uses). The LOGIC is the reference's and is identical in
  user-app-v2; only the styling differs between the two apps.

  Kept from the reference:
  - the title "سفارشات مشتریان" (ChildOrders.vue:18)
  - the search box over the list (:26)
  - infinite paging: one page per scroll to the bottom (:327-338)
  - per card: "سفارش : ORD-{id}", the item count, the total weight in grams,
    the customer name, and the fixed status chip «تحویل مسئول فروش» — the
    reference hardcodes that label (:48) because the endpoint only ever
    returns orders at that status (`where('sts', 5)`, ApiMobileController:766)
  - the card is tappable, as the reference's was (:29)

  Deliberately NOT ported: the reference's edit-order drawer behind that tap
  (toEditOrder -> PUT /order/child/{id}) recalculated an order's weights and
  prices from values the CLIENT sent. Bringing that across during a delivery
  would put a money path in the app with no server-side recomputation; the tap
  opens a read-only summary instead. Recorded in D21/DELIVERY.md.

  Scope is the server's: every row belongs to a customer this expert referred.
  No id travels from the client.
