The CMS answers a capture of an order already paid with this PayPal order
with { success: true, alreadyCaptured: true } instead of the order. Step 3
took that answer for a capture without authorisation and showed a payment
error. It now reloads the paid order (keeping the shown one if the reload
fails) and continues as after a first capture: confirmation, the
checkout-payment-completed event, and the redirect to the order's result
page. capturePayment is typed as Order | AlreadyCaptured, and the pure
isAlreadyCaptured (utils/captureResponse.ts) tells them apart.
