This is a first pass at removing unused jslib code from directory-connector - specifically, unused services.

My strategy here was to iteratively delete services (both the abstractions and implementations) which were unused by any other class. Carving up partially used services was out of scope - I was only removing services that were wholly unused. After doing this, I used depcheck to identify unused dependencies and removed the couple that I could.

This is a huge diff but most of it is just file deletion. There is no refactoring other than to update dependency injection to no longer instantiate these deleted classes. The proof is largely that the build still passes and the app bootstraps OK.

I have not removed non-service code. Most models are imported by ApiService and StateService - that is probably a separate effort to extract what's actually used from those classes.
