Per feedback the 待支付/售后 shortcut row is not wanted. Remove the nested
quick grid, delete the now-orphaned sidebar-orders renderer, and strip its
uc-order-grid CSS. 我的订单 remains a single tile in the 我的服务 grid.
The standalone order card is folded into the 我的服务 (My Services) sidebar
section: 我的订单 becomes a service-grid tile (all orders), with the
待支付/售后 quick shortcuts rendered beneath it as a compact row. Gated on
the orders dashboard tab being registered so no dead tile appears when the
payment stack is absent.
