Upload New File: Permissions and Error Messaging

Problem Statement

From the dotCMS backend, I would like to prevent content editor from being able to access and use the "Upload New File" button from within an image field in a content type. If I don't give any permissions to content editors to the default File Asset content type, I would expect them to get an error message when they attempt to do so. However, current behavior is that it will appear content editors are able to upload an image, no error is shown, but no image ever gets uploaded. It's good the image is not uploaded, since the content editor doesn't have permissions, but this is confusing behavior as the user has no indication of an error and would continuously try to keep uploading the image.

N/A

Start by reproducing the Upload New File flow from an image field as a content editor without permissions on the default File Asset content type. Trace the permission failure and verify that the UI displays an error when the image cannot be uploaded; the acceptance criterion is a clear error message instead of a silent failure.
