`superusers.index` view 500s and maybe isn't useful

Why are we doing this?

There is a superusers app with an index page that tries to list all organizations, users, and their codelists. This shows some extra info over the main index/home page which only shows codelists attached to an organisation. However, it currently doesn't work against the production database, returning a 500 error. And it's not clear if it's useful/used. Why do we need this view on codelists? Is anyone using it (presumably not, as it's broken. Would anyone like to?).

Maybe we should have an admin view on the site, but if so it might not look like this one and we might want to design it from scratch. Also, I'd rather we build it by extending the Django-provided django.contrib.admin, which is very robust, flexible, and probably supports our needs.

Sentry error (triggered by Mike).

The URL on the prod site: https://www.opencodelists.org/superusers/

How will we know when it's done?

We've figured out if anyone uses this view and would like it working (check Sentry/Honeycomb for accesses, ask in #general?).

The page either works in production, or the app has been removed.

Possibly future issues created for admin functionality on the site.

What are we doing?

As above, TBD.

Defining delivery tasks guidance

Start with superusers/views.py and the superusers/index.html template, then inspect codelists/models.py at get_absolute_url and the user_version URL pattern. Use the Sentry stack trace to reproduce the production failure and check Sentry or Honeycomb for usage, with the project discussion deciding whether to fix or remove the app. Done means the view works in production or the app has been removed.
