Closes #9844

Technical

Builds on PR #9797 , which should be merged first and this PR rebased for ease of review. #9797 changes very many test files, this PR modifies fewer and should be more contained to address just #9844.

Now that #9797 has been merged, I have rebased this and it looks a lot neater, and makes it clear what is changing with contributor roles. Selected abbreviations are expanded from the full list to controlled contributors, and also some common ones from the freeform text of $e subfield.
