Add toggleable pierce point drawing to PlateView that shows small red
filled circles at each rapid move endpoint (where cutting begins). Wire
through View menu, EditNestForm toggle, and MainForm handler.
Also rename RectangleShape/RoundedRectangleShape Width/Height to
Length/Width for consistency with CNC conventions, update MCP tools and
tests accordingly. Fix SplitDrawingForm designer layout ordering and
EntityView bend line selection styling.

FlangeShape generates an outer circle with evenly-spaced bolt holes
on a bolt circle pattern. ShapeDefinition.LoadFromJson<T>() provides
generic JSON loading for any shape — no separate preset classes needed.
