leaderboard: axis gizmo on task render grids; bump cadgenbench

tasks.py overlays the shared XYZ orientation gizmo on the editing task's
starting-shape render grid (imported from cadgenbench.common.axes_gizmo).
Bump CADGENBENCH_SHA to 193f2f5 so the Space's report generator picks up the
gizmo + headline-pill changes and tasks.py can import the helper.
