[Shipping labels] Add UI to display address verification status and save button

[rachelmcr]

Part of: #13781
⚠️ Depends on #14847 ⚠️

Description

This adds the bottom section of the edit address screen in the Woo Shipping label flow. There are three possible states for the UI:

• If the address is verified and unchanged, it shows "Address verified" in green with a "Close" button to dismiss the sheet.
• If the address is unverified (e.g. it has been edited) and is not missing any information, it shows "Unverified address" in red with a "Validate & Save" button.
• If the address is missing required information, it shows "Missing information" in red with a disable "Add Missing Information" button.

The status is based on a status property in the view model. For now, this is set depending on whether the address is already verified. Future PRs will add more logic to set the status based on whether the address has changed and local validation.

Testing information

1. Ensure the latest production version of WooCommerce Shipping (Version 1.3.2) is installed, activated, and set up on your store.
2. Create or open an order with at least one physical product and the processing status.
3. Tap "Create Shipping Label" in order details.
4. Open the "Shipment details" bottom sheet.
5. Tap the "Ship from" origin address.
6. Tap the edit (pencil) icon on one of the origin addresses.
7. In the edit address sheet, confirm a status label and button appears at the bottom of the form.
8. Confirm you can scroll down to view all of the form fields.
