fix: refresh payment methods after user adds a payment method

If methods doesn't include the paymentMethodId, the Payment method input will show "No saved payment methods".

Since paymentMethodId gets set after a user adds their payment method, we can listen for when it's set and fetch the methods if the newly added payment method isn't in the original list of payment methods.
