Title: Upgrade step to fix env UUID for minUnits

The environment UUID migration work for the minUnits collection missed a change to add environment UUID to new documents. This means minUnits documents added after the migration work landed will have a blank env-uuid field.

This change adds an upgrade step to repair this (the missed code change has already been corrected).
