[batch-f] Extend CardSelectionSheet test into PaymentCardView

testConfirmarEPagarWithCreditCardOpensCardSelectionWithoutSubmitting now
also taps CardSelectionSheet's "Adicionar novo cartão", which opens
PaymentCardView (CheckoutView.swift's own card-entry form - a distinct
struct from AddCardFormView.swift, which is a separate screen reached
from Profile -> Meus Cartões and already covered). Doesn't fill or
submit anything, just reaches the form and dismisses back through both
sheets.

Extracted the shared "x" close-button dismiss logic (used by both
CardSelectionSheet and PaymentCardView) into a private
dismissViaCloseButton helper.

Verified stable across 2 consecutive class-level runs.
