fix(ui): show /clear before command in Next Up blocks (#1623) (#1631)

The Next Up blocks showed the main command first, then /clear as a <sub>
footnote saying 'first'. Users would copy-paste the command before noticing
they should have cleared first. This restructures all 41 instances across
19 workflow files and 2 reference files so /clear appears before the
command as a clear sequential instruction.
