Single Product Auto-Selection in Builder Preview

In the builder preview, when only one product was added to a form, it was not automatically selected, leading to confusion during the checkout process.

Now, if there is only one product, it will be auto-selected for both payment and order summary, eliminating the need for manual selection.

1. Auto-Selection: The single product is selected by default.

2. Simplified Checkout: Users can skip the unnecessary step of selecting what is already evident.

3. Applies to All Types: This feature works with both radio and checkbox product options.
