[Hackathon doc sprint] Beginner documentation about constraint reports
Open, NormalPublic

Description

Right now, there is nothing at Community Portal, and no easily findable info about what a constraint report is, why it's important, what to do about constraint violations, and how they are generated from Property Talk pages.

A basic starter page about this would be valuable. Closest that we have now:
