fix: typo and minor improvements

[volmedo]

when I ran make init from my clean environment as the first step to deploy my dev env, I was presented with a message from tofu init because I had TF_WORKSPACE=vic in my .env.terraform file but the workspace didn't exist yet. I think the solution is to force TF_WORKSPACE=default in the init for the app folder too, as is done with the shared folder.

I also added .PHONY targets for the init tasks so that they are always run. There are some situations where modules need to be updated and a new init is required.

This LGTM although i can't really speak to the phony tofu init - do we really want to run these every time? What if a new target instead that forces?

you are right. I looked for dependencies on init and didn't realise other tasks depend directly on app/.terraform. I'm removing the phoniness for now.
