Finalize Documentation

Docs are mostly done. I am leaving this open for the following things, that I am not going to create sub issues for yet, but may after we meet:

• We may want a IAMFrontend.
  • May=Definitely do. This will require essentially a full rework of the Frontend-Implementation doc
  • This will also require a rework of the Keycloak-Implementation doc, particularly the client section. I have created a v2 of the doc in case we want to replace it.
• Given this work, we may want to add a Future-Work doc that outlines where we left off. This would include things like:
  • adding tests for iambackend in testrunner
  • adding iamfrontend if I dont get to it
  • Complete list of doc refactors needed
