pathways: glowing edge segments only appear on hover; drop the preview fade

the edge marker is drawn on the tile and the ghost renders in the gap, so
they never overlap - there is no reason to fade the edge while previewing,
and the .preview class was making the edge vanish exactly when hovered. edges
are now invisible at rest and glow at full strength on hover.
