fix(ui): translate order status and payment method to Vietnamese
- ShopHelpers: add OrderStatusLabel(), OrderStatusBadge(),
PaymentMethodLabel() — translate raw status/method strings
to Vietnamese with correct badge colors

- ShopOverview.razor: same status translation
- ShopReports.razor: same status translation
- CafeDesktop.razor: update MapApiStatus() to include
Draft/Validated/Paid/PaymentPending mappings;
update MapPaymentMethodLabel() to include qr→"Mã QR",
transfer→"Chuyển khoản", vnpay/momo, empty→"Chưa thanh toán"
4 payment methods supported: Tiền mặt, Thẻ, Mã QR, Chuyển khoản
