Thanks, this looks mostly good to me.

Could you also verify that the a message is shown that the page is not in translation if the page was not in translation before, and that a message is shown that the status was successfully cancelled if the page was in translation before?

For reference, you could do something like that: https://github.com/digitalfabrik/integreat-cms/blob/develop/tests/cms/views/feedback/test_region_feedback_actions.py#L55-L59

Thank you for the suggestion regarding the log messages.
I will implement it accordingly.

Regarding the archived pages:
There were some problems with other tests not passing, because the new pages were pulled into those tests and messed with the expected results.
There are many necessary changes and I haven't found a solution to some of them, yet.

I have added the checks for the log messages.
During my tests, the messages were in German, so I had to add support for English and German log messages.

I also un-archived the pages and moved them to the Nürnberg region to reduce the impact on other tests.
This worked well, but the Editor and Management roles don't have the necessary rights in the Nürnberg region,
this would have to be added in the test_data.json. (But the side effects here are unclear to me, so far.)

We can specify the language of error/success messages. See those lines
(settings: SettingsWrapper must be then included into the parameters of the test function)

Thank you for the hint. I was already wondering.
