Initial (editable) pass of adding JT.organization

This is the old version of this feature from 2019
  this allows setting the organization in the data sent
  to the API when creating a JT, and exposes the field
  in the UI as well

Subsequent commit changes the field from editable
  to read-only, but as of this commit, the machinery
  is not hooked up to infer it from project
