Add card in site in the payment method

[jimmyn]

1. Let's rename default "Pay with MONEI" to just "Credit card" so it is clear to the customer what the payment method is. In the redirect mode, the default text should be "Credit card and other payment methods" so it is coherent with other payment method names
2. Limit the card input max width to 500px, is it possible to use the default input styling from the theme so it matches the rest of the UI?
3. We need to add cardholder name input above the card. Prefill it with the name from the billing details, if present. Here is the guide how to send it - https://docs.monei.com/docs/guides/send-cardholder-name/.
4. Show the loading spinner until the confirmPayment promise is resolved, so it is clear that the payment is processing, check how it works in demo - https://github.com/MONEI/monei-payments-demo/blob/master/public/javascript/payment.js#L202

@jimmyn card. Not Credit Card

It is still a convention to call it Credit Card, take a look at Shopify
