style(layout): the whole row is the drag handle

A list whose rows can only be moved by a sixteen-pixel grip is a list
most people conclude cannot be moved at all. The grip stays as the sign
that it can, and the row itself now carries the gesture — plus a line on
the edge the row would take, because the question a dragging hand asks
is 'between which two', which a highlighted target does not answer.
