Adjust order address form to improve its styling

[krzksz]

Description (*)

This PR aligns the looks of order address edit form with a new order creation shipping and billing
address forms as they share block's class parent and logic.

Fixed Issues (if relevant)

1. Sales order Address Information edit form layout design improvement. #19805: Sales order Address Information edit form layout design improvement.

Manual testing scenarios (*)

1. Open order information and edit shipping or billing address.
2. Address edit form styling shouldn't look broken and be simillar with new order creation address forms.

Questions or comments

My initial idea was to align the looks of the form to customer address edition which is opened inside a modal but it turns out that the same logic and blocks' parent is shared between existing and new order address edit forms so I just made sure they look similar:
