[Zurich] Admin interface for managing hierarchical attributes

[chrismytton]

[edit: This PR now also incorporates #5631 and #5635]

Interface allows creation, editing and deletion of attributes associated with a division. These attributes will then be added to the admin report screen to allow admins to update these attributes before the reports is reassigned to a subdivision.

Looks good, only some small display suggestions :)

Woo, thanks!

Sorry, only spotted this while reviewing the other PR. They said in the quote the name for the 'sub' tables is non unique, which I took to mean that you could have two entries in e.g. Objekt with the same name but in different Geschäftsbereich. I thought I had tested this here, but it doesn't seem to work so perhaps I didn't - the "already exists" check here should only be unique per 'parent' if there's a parent, I guess fixes it? Done in fixup

Nice, thanks! 👍
