[batch-f] Add CardSelectionSheet test, fix product-row plus-button bug

Adds testConfirmarEPagarWithCreditCardOpensCardSelectionWithoutSubmitting:
selecting Cartão de Crédito and tapping "Confirmar e Pagar" opens
CardSelectionSheet (a separate struct in CheckoutView.swift) rather than
submitting an order - confirmed by reading
CheckoutView+Logic.handleConfirmPaymentTap(), which returns early before
any order-creation code when useInAppPayment && paymentMethod ==
.creditCard. Dismissed via the sheet's own close button, never selects a
card or submits anything, consistent with the earlier explicit user
direction not to create real order data during this coverage push.

Real bug found and fixed: reachCheckoutWithOneItem's product "+" button
selector (app.buttons.matching(identifier: "plus")) is the same class
of bug already fixed for the tab bar's cart icon - once a product's
quantity is > 0, its outer Button's identifier moves off itself onto a
nested Image (the row's own quantity Text takes over the Button's
accessible identity). This broke today specifically because the
standing QA account's cart has genuinely accumulated real quantities
across many runs, eventually leaving no untouched (quantity == 0)
product for the old selector to find - confirmed via screenshot showing
the "+" controls clearly rendered on screen while the buttons-only
query found nothing. Fixed by targeting the nested Image's identifier
directly (app.images.matching(identifier: "plus")), same fix pattern as
the cart-tab icon. This is shared by all three tests in the file via
reachCheckoutWithOneItem.

Also bumped two real-network timeouts based on trace evidence (not
guesses): store-detail load 15s -> 25s, OTP-request-to-Verificação-screen
15s -> 25s in UITestSupport.ensureLoggedIn.

Verified: the new test passes consistently in isolation and alongside
the other two tests in the class. One remaining flake
(testAddProductToCartAndReachCheckout hitting "Login never completed"
when run back-to-back with two other real-login tests in the same
invocation) confirmed via isolated rerun to be real backend load from
three consecutive real login/logout cycles, not a code regression -
passes cleanly alone.
