Order details: Display all items in a shipment when there are no created shipments

[itsmeichigo]

Closes WOOMOB-1011

Description

This PR updates the order details screen to always displays the shipping labels section if the order is eligible for label creation.

The old button and info for creating labels in the Products section have also been removed.

Testing steps

1. Log in to a test store with Woo Shipping setup.
2. Navigate to Orders tab and create an order with physical items.
3. Update the order status to processing or collect payment for the order.
4. Open the order details and confirm that the Create shipping label button is displayed in the Shipping labels section.
5. Optional: purchase a label for the order with all the items (without splitting shipments). Confirm that the order details screen then displays the purchased label in the Shipping Label section.
6. Open another order with only virtual products and confirm that the shipping label section is not displayed.

Testing information

Tested and verified on simulator iPhone 16 iOS 18.2.

@itsmeichigo should we hide the button also for users using the old plugin? I assumed the new UI and all the changes should be applied only to the new plugin. This change breaks the functionality completely for old plugin users, there is now way to start shipping label creation, as we try to open the new form but it fails.

Thanks for catching this issue! I prefer to unify the UI to make the code easier to maintain, so I removed the workaround for woo shipping check in 4b251a6. This was added when I introduced the new UI and is no longer needed with the changes in this PR.

This PR is ready for another look 🙏

@itsmeichigo I think there is still an issue, we show the new UI even when the order has existing shipping labels, and then there is now way to print the labels nor see their details, this happens a short loading where the labels are correctly shown as you can see from the following video:

For information, this site had Woo Shipping installed before, and I disabled it, in case this is necessary to reproduce the issue.

[itsmeichigo]

Sorry for missing that issue. I added a fix in 640a385, it should avoid creating shipments for the legacy plugin. I tested with multiple packages and that works as well.

Works well, thanks @itsmeichigo for addressing the issue I reported.
