Sidebar improvements

[abc013]

Closes #353.

Furthermore, this PR streamlines the minute and information page sidebar layout (see second commit) and also adds empty date or editor handling.

I was unable to test some of the changes, specifically those about the minute sidebar. Before approving, please check whether everything looks as expected. I'm investigating why minute pages don't work (even on main) on my local setup.

It would be helpful to have a list of changes that are supposed to work to test them (if automated tests are not an option).

[jeriox]

additional idea: display a warning banner or some indication in the sidebar for pages that are a draft (similar to the exclamation mark in the list)

@jeriox good idea. I added it in e56ed7d:

@abc013 is the description of the PR still correct or could you test your changes locally in the meantime?

I would say I was able to test most of it, but would be happy to have someone with a proper database looking over it. My test minute pages are quite empty. :D

With #444 merged, you should now be able to create somewhat longer minutes automatically.
