fix(workplans): re-key WHYNOT-WP strays onto WNCTL-WP

WHYNOT-WP belongs to whynot-design (26 ids vs 6 here), ruled by Bernd. The two
repos were cross-blocking in the hub: whynot-design could not claim
whynot-wp-0001 because this repo held it, and this repo could not claim
whynot-wp-0002 because whynot-design held that.

WNCTL-WP is newly registered to this repository. Numbers carry over unchanged
since nothing here used the new prefix. Both files declare repo: whynot-control,
so this is the repo's own work, not inherited template residue.
