refactor(render): carry panel insets as Scene.TileInset

TileInset replaces TileClip: zero means no panel, and insets covering
the output mean no room for tiles, so core no longer hides tiles by
hand. Scene.Draws and Scene.TileArea own the rule. The renderer cuts
tile lines and damage at the tile area too, the overlay plane skips a
tile wholly under a panel instead of picking it, and Rect.Contains
replaces two copies of the containment check. The focus pulse needs
room to be drawn.
