Delete the legacy fill and stroke paint markers

The appearance column is now the only paint channel. The Fill and
Stroke attribute markers, their name constants, the LanePaint push with
its two-hop reach, and the interior paint placement all go away; nodes
emit and readers cascade the appearance alone. PaintReach shrinks to
the cascade's own-wins arbitration, the legacy conversion converts the
group content inside appearance paint cells, and transform baking lands
on those cells too.
