add loading for hide/show/delete of expert, show expert sections with…

… no data when editing

This will include updates for the following:

• [x] This comment @Vensberg mentions changing "private" to "internal" in the delete modal for experts, as well as that the visibility icon was not updating until page refresh. I think the icon not changing was because the request to authenticate in CDL took a few seconds, so I added loading animations to the visibility/delete actions.
• [ ] @wrenaria mentioned to add No data to display to sections of the expert profile if there is no content, so the user can navigate and populate this data. This will show up only when editing/impersonating, for Introduction, Roles and Links.
• [ ] While testing the previous item, I noticed if you hide all works or grants, when editing/impersonating, the headers with links to edit the works/grants disappear. Now it will show 0 Works/Grants and show the hidden works/grants, and have links to the edit pages.
• [ ] Kimmy also mentioned to update the My Account quicklinks header nav to include a profile image for clarity.
• [ ] The expert visibility/delete buttons were showing up for all experts if the user is an admin and is impersonating anyone. Now they will only show up for the expert that's being impersonated.

• [x] Changes in visibility in test AE successfully changes all aspects of the user's profile in QA Elements to internal, including relationships to works and grants

@UcDust , I'd like to rework the Hide Expert message content. Can you make it: Expert will be hidden from Aggie Experts. In the Publication Management System their privacy will be set to internal. To show the expert again in Aggie Experts, you change the privacy in the Publication Management System to public or contact an Aggie Experts administrator. Are you sure you would like to continue?

@UcDust reversing from invisible to visible throws an error. Can you make that waiting period longer? It worked well for the invisible. I will hold on testing deletion, but their wait periods should probably be adjusted, too.

Now the invisible-->visible works

[Vensberg]

Based on https://github.com/ucd-library/aggie-experts/pull/358, the message for visible-->invisible should be: The expert will be hidden from Aggie Experts, but this change will not appear in Elements. This is a safeguard available only to admins, in case "Delete Expert" does not work because Elements is not reachable. It is the admin's responsibility to manually change visibility in Elements.

Based on that, the connection between the visible icon and Elements should be removed.

[Vensberg]

For deletions, the message should be: The expert will be removed from Aggie Experts. In the UC Publication Management System their privacy will be set to internal.To show the expert again in Aggie Experts, you would need to update the privacy setting to public in the UC Publication Management System. Are you sure you would like to continue?

@Vensberg this should be deployed to test for tomorrow.
