show namespaces alongside url_name in request panel

[AlexCLeduc]

As far as I know, no one really asked for this, but I work on projects that make heavy use of namespaces with repetitive urls (e.g. create, edit, index) and having namespaces available in the request panel helps disambiguate and makes for a quicker grep.

Before this PR:

After this PR:

I used : as a separator because that's what you'd pass to e.g. reverse("admin:login"). We can alternatively add a separate 'namespace' title/content section, but this seemed cleaner to me

Thanks, this is great. I think including namespaces directly in the URL name is fine.

However, the new test seems to fail quite often. @AlexCLeduc Do you have an idea why?

@matthiask Sorry about that, I had trouble running tests locally and figured CI was misconfigured. Turns out the test app never included the admin URLs, looks like it works now.

[tim-schilling]

@AlexCLeduc If possible, could you move this test to the RequestPanelTestCase test case in tests/panels/test_request.py? If we don't need it in the integration test case, I'd like to avoid that.

Thank you! 💪🎉
