Fixing inconsistent prev/next navigation buttons

[olemartinorg]

Description

I've observed that the previous/next navigation buttons sometimes mysteriously disappeared, and I was about to create a bug report for it. However, to figure out if it was just my config that was wrong, I looked into it and quickly found the cause behind the problem - these buttons seem to somewhat rely on a navigation property set in the layout file (which is an undocumented feature?!). I'm a bit confused about what was supposed to happen here, so I'm opening a draft PR to get some feedback. These changes seems to work in the same way the documentation describes, though.

Still not sure about this one. I think I have to go sift through the code to fully understand how these things are expected to interact with implicitly added submit button(s), etc.

Potential breaking change. Will be merged when we introduce V4 of App Frontend.
