Improvements to the "Shipping cost" field in the "Shipment" settings

We have changed the design of the “Shipping cost” field, allowing you to choose from multiple options: “Fixed price,” “Hide the price,” and “Custom price.” The fixed price will be added to the order summary, while the custom price allows you to display individual text. This update allows you to select the most convenient methods of calculating the shipping price, which will improve the interaction with clients. Store management became even more comfortable.
