fix: custom close for card

[hhumphrey-ledger]

📝 Description

Using navigation.popToTop works in buy/sell as we have no additional routing within the app so it is not intercepted by this listener and it successfully goes back to the homepage

Swap has additional routing and our history stack can get messy. Doing:

navigation.getParent()?.navigate(NavigatorName.Base, {
    screen: NavigatorName.Main,
});

Forces us to load the main screen and unload swap
