Issue: https://www.drupal.org/project/ai_media/issues/3634859

When the Generate request failed in the browser (network error or non-2xx), the button came back and the failure was only announced, so a sighted editor saw nothing.

The message "This could not be made. Try again." now shows as an error below the description, on both the Media Library and the Add media page, and goes away on the next press.

Before: a failed Generate request shows nothing on the page.

After: the error shows below the description.
