Expose org management links to MuckRock staff

[allanlasser]

As a staff user, I can view the org editing and member management pages, but I can't find them from the frontend.

When I search for an organization to test this on and click on the organization, I receive a 500 error. https://muckrock.sentry.io/issues/7122148094/?project=1247105&query=is%3Aunresolved&referrer=issue-stream

@duckduckgrayduck Great catch, thanks. I just pushed up a fix and an accompanying test for this crash.

Since this is a staff action, we should also log it similar to hijacks and editing a member page as a staff user. This is new_action in core/utils.py

@duckduckgrayduck I agree with you, but I'd prefer to introduce that separately. This PR is intended to reveal the links to staff users as a short-term fix, and we've got updated handling for these pages in our redesign-orgs branch. Creating a small task to log staff interventions feels like an easy, worthwhile addition to that release. Are you ok with deferring this until then?

[duckduckgrayduck]

That's fine with me
