AP: Apply the design updates

[valterlorran]

Closes #97082

Proposed Changes

• Fix the icons on the Authorization Step.
• Fix the error message in case we can store the Credentials.

Why are these changes being made?

• There were a few outstanding design issues that we needed to tackle separately, beyond that we collected feedback to the new error we introduced.
• p1733342097901209/1733315236.570409-slack-C0Q664T29

Testing Instructions

• Use calypso live to avoid the SSL error when trying to authenticate.
• Go through the migration process until you reach the Credentials step.
• Then update the URL to point to the /setup/site-migration/site-migration-application-password-authorization path. Keep the current parameters, and add the authorizationUrl, which could be a valid authorization URL for the Application Passwords: https://example.com/wp-admin/authorize-application.php&app_id=1083d914-d9f8-47ec-b49b-55d206104730&app_name=Test
• You should see the default view, inviting the user to Authorize. Click on the "Authorize" button.
• You should be redirected to your test site.
• Approve the new Application Password.
• You should be redirected to the Authorization step and should see a loading state.
• After the loading state, you'll probably see the Authorization step with an error message, because the endpoint that stores the Password will fail because you don't have the ticket.
• So far this should be enough to test.

I followed the instructions and got the success screen.

I don't see any ticket open on Zendesk for me even with the search. But I suspect that maybe I have a open ticket, that is not appearing on Zendesk at the moment. Let me dig a bit more into that.

The CI errors seem related to the diff
