Changelog: Fix - PayPal express payments on block checkout now complete the order directly when Pay Now is enabled #4790

Description

🐛 The problem

With the v6 SDK and Pay Now enabled, a buyer who pays with the PayPal express button on an empty block checkout form lands on the review page instead of the Order Received page. They must click "Place order" a second time. With the v5 SDK, the order is placed directly.

💡 Why it happens

After approval, the v6 express component sent the PayPal addresses to the server but never put them into the Blocks checkout form. The Store API response strips billing and shipping, so the form stayed empty. The automatic submit then failed validation, and the validation fallback redirected the buyer to the review page.

✅ The fix

V6ExpressComponent now also writes the PayPal addresses into the Blocks form state (reflectInUi: true) before it submits. v5 already did this, and the v6 review page does the same.

🧪 How to verify

1. Enable Pay Now and SDK v6, and use block checkout.
2. Add a simple product to the cart and open the checkout page. Leave the form empty.
3. Pay with the PayPal express button. The Order Received page opens.
4. Disable Pay Now and repeat. The review page opens, with the PayPal address filled in.
