fix(ui): point operator messages at commands that exist

Pinned-lead and locked-lead warnings named a Drawing Pins Off command and a
Clear Lead-ins command that the desktop does not have; name Plate > Remove
Lead-ins and spacing instead. Closing Plan Cutting no longer claims nothing
changed after lead-ins or cut-offs were cleared, the no-stock reason no
longer says the part is larger than every sheet when only the usable area at
the checked rotations is too small, and the console says whole-job engines.
