fix: review follow-ups for #1602 and #1606

- #1602 changed the COMMANDLINEFADETIME help text and added "Never"
  without catalog entries, so both showed in English everywhere. Add
  them to the catalog and all 21 locales; drop the "0 skips them" key.
- #1606 named another CAD vendor in a doc comment and two test names.
