The extend-X / extend-Z icons in GizmoWallEdition's cursor row are billboarded toward the camera; without orientation polish they always point in the same screen-space direction regardless of which wall endpoint the click will move (or whether the cursor sits above or below the wall top). New helper mirrors the icon's local-X (extend-X) or local-Y (extend-Z) axis so each arrow points toward the end it will move: * Extend-X: walk wall midpoint to figure out which endpoint stays fixed (cursor past midpoint → ATSTART stays; cursor before midpoint → ATEND stays). Project the fixed endpoint into screen-space and flip the arrow when the gizmo's anchor sits on the same side. * Extend-Z: flip when the cursor is below the wall top (within EXTEND_FLIP_EPSILON tolerance). Called once per resolved cursor gizmo from ``GizmoWallEdition._update_cursor_gizmos``, after the gizmo's ``matrix_basis`` is set by ``gizmo.billboarded_at``. Reuses ``gizmo.should_flip_extend_arrow`` + ``EXTEND_FLIP_MIRROR_X/Y`` + ``EXTEND_FLIP_EPSILON`` already on tool. Generated with the assistance of an AI coding tool.
