Make improvements to the Users admin page

[lucasmarchd01]

There are a few things that we should do to improve the admin user page to make it more understandable.

• [x] We should display the full name on the list page
• [ ] We should move the users with is_indexer=True to a new tab under Users (probably called Indexers) that will hide them from the regular users list page
• [x] For indexers, we should display their full name instead of the fake email

We should display the full name on the list page

This is an easy "yes, let's do this"

We should move the users with is_indexer=True to a new tab under Users (probably called Indexers) that will hide them from the regular users list page

I know I was the one to suggest this, but I'm not 100% sure that this is the right thing to do. @annamorphism, do you have any feelings about this one? Should we check with Debra?

For indexers, we should display their full name instead of the fake email

If indexers are on a separate page, then yes; otherwise, I'm not sure that hiding the email address is the right choice. This one depends on point number 2.

the remaining item in the checklist above feels complicated, and doesn't strike me as necessary. setting this to priority: low.
