Great to finally see this. I just had some passing comments that you don't need to address if you don't want to.

This is one of the commits extracted from #2334, which works towards doing diagram chasing. It has been extended with a few more tests and a couple of clean ups.
It sets up the theory of wild categories enriched in abelian groups. Within AbEnriched.v, the theory of a 0-groupoid abelian group is set up. If it's needed elsewhere in the future, it could be factored out. Also, if we ever need non-abelian 0-groupoid groups, we could easily remove commutativity, and add it in a second layer. But for now, I kept things to what we need for diagram chasing.
