wip(lab): Work on workbench

- Moved the various tabs on the draft view to their own views.
- Renames modes to views
- Started to group various aspects of the workbench state under
  `_state` in the gist to prevent it from getting all mixed up
  with the core settings.
- Updated events title to make it more clear not all events might
  be present
- Removed valid state in measurements input since it was only
  getting updated on keyboard input but now when preloading
  measurements (which it does now)
