Problem statement

Currently we need to reload pages/run constant fetching to get results of long running tasks/changed page details. That leads to unneeded traffic.

Suggested solution

After #6173 is merged we can introduce websockets and use them for notifications, progress bars, page indiactors and more

Describe alternatives you've considered

Sounds like that would offer a huge improvement!

This depends on the migration to Django 4 but after that it should be simple - I have a bunch of projects with this setup. I can just borrow the structure from there.
