feat(cards): implement full saved card management and transparent checkout

- ApiCardModels.swift: SavedCard, SaveCardPayload, CreditCardOrderPayload, etc.
- ApiOrderModels.swift: add savedCardId, clientCpfCnpj, creditCard, creditCardHolderInfo to CreateOrderPayload; Codable for item/addon payloads
- ApiService.swift: listCards, saveCard, updateCard, deleteCard, updateProfileCpf
- AppState.ProfileState: add cpf field
- CheckoutView: CardSelectionSheet (list saved cards + add new), rewrite PaymentCardView (submits order with card data), CardPaymentContext carries full order data
- CheckoutView+Logic: buildCreateOrderPayload accepts card params, new loadSavedCards/confirmOrderWithSavedCard/handleOrderResponse helpers, redirect credit card confirm to CardSelectionSheet
- OrdersView: CREDIT_CARD pending orders go to tracking (not card form, since card is now submitted with order)
- UserProfileView: CPF field with mask, save via PATCH /api/customer/profile
