M4: Boolean groups: test the one-radius panel through corner smoothing (#2222)

The field test's "no field per corner" check passed for any shape, since corner fields are built
only while the individual-corners popover is open. A boolean group's button now has its own test
beside the polygons' (shared helper): it is named Corner smoothing, opens no corner fields, and
sets the smoothing in one undo step. ROADMAP's status line reads minor, as the other docs do.
