CAM: Fix Helix Defaults in Setup Sheet

With PR #17655 (commit 1027926), the property "Direction" was changed
being an input to an output and the new "Cut Mode" took over (to
implement #14314). Unfortunately, this change was not reflected in the
Setup Sheet (or "Op Defaults" as it's called on the Job panel). This
commit fixes this.
