Following up on #11124.

The longer term goal is to develop C^* algebras, where non-unital algebras are an essential part of the theory.

Unfortunately add a few more steps to the hierarchy makes a few more unification problems fail, so much of this PR is patching up proofs that used to work. Hopefully none of the patches are too unpleasant?

I'm encouraged by the fact that we seemed to need only 8 patches in a codebase with c.800k lines.

Thanks for doing this. (I wonder what will happen when we want to talk about commutative non-unital rings 😨)
