PAY-2067: Block links & pledge button when loading PaymentSheet

[Arkariang]

📲 What

When the user hits the New Payment method button, a network request takes place, but the user could still hit pledge, or some of the link to "Learn more about acountability", "Tems of use, Cookie policy" ... etc

Now the links are disabled alongside the pledge button until the PaymentSheet is presented

🤔 Why

• Avoid the potentially presenting the paymentSheet in a wrong screen, or once the user has already pledge.
