JSDoc: Update so it actually works

Now that we have a process, use this to track the progress.

Will create config files and update test.user.js to start.

Since we are unable to run jsdoc locally (older OS), we will do the following:

1. Create throw-away branch for module being updated
2. Update config to cover the next module and push to branch (use git push --no-verify to avoid version checks)
3. Incrementally address errors and push branch until module passes
4. Incrementally improve doc coverage and push branch until happy
5. Manually copy (NOT merge) improved module and config back to main
6. Delete throw-away branch both locally and on GH

No immediate plan to actually publish the docs. That is likely to come later.
