Number cards ride along on edge and cell casts

The edge-click dispatch attached the tapped number card only for
wall attacks, so the warp wand's first use could never receive its
charges ("a wand's first use needs a number card" no matter what),
and wall of fire silently burned one turn instead of its NUMBER.
Cell-target casts had the same gap for duration terrain. The attached
number now rides every edge and cell cast.
