Skip confirmation page in Express checkout

To place an order from the PayPal modal, skipping the confirmation page, use the useConfirmationPage property of the PaymentPaypalExpressProvider component:

<template>
  <PaymentPaypalExpressProvider 
    :afterPay="afterPayAndOrder"
    :afterRedirect="toggleCartSidebar"
    :useConfirmationPage="false"
  />
</template>

Add afterPay and afterRedirect handlers. You should hide the sidebar inside both of them if it's shown. Use code from Usage on the frontend step to prepare callback functions.

WARNING

If there is a malformed price error, a component will redirect a user to the URL configured in the checkoutSummaryStepUrl field. You should have a PaymentPaypalProvider component that will handle the rest because our integration fallbacks to the classic PayPal flow described here.
