ShapeProfile.NormalizeEntities called Shape.Reverse() which flipped arc
directions on the original entity objects shared with the CAD view. Switching
to the Program tab and back would leave arcs reversed. Clone entities before
normalizing so the originals stay untouched.
Adds abstract Entity.Clone() with implementations on Line, Arc, Circle,
Polygon, and Shape (deep-clones children). Also adds CloneAll() extension
and replaces manual duplication in PartGeometry.CopyEntitiesAtLocation and
ProgramEditorControl.CloneEntity.

Switch gcodeEditor from TextBox to RichTextBox and colorize G-code
tokens: rapids (amber), linear cuts (green), arcs (blue), comments
(dim gray), and mode codes (purple).

Remove the Apply button and OnApplyClicked handler since the gcode
editor is now read-only. Add contour label comments (e.g. "; Hole 1
(CCW)") to the formatted gcode output so users can see which feature
each group of codes belongs to.

Switch colorsList from CheckedListBox (which silently ignores owner
draw) to a plain ListBox with manual checkbox, color swatch, and hex
label rendering. Clone entities in ProgramEditorControl preview to
avoid mutating originals. Remove contour color application from
CadConverterForm. Fix struct null comparison warning in SplitDrawingForm.

- Replace Program.ToString() with Cincinnati-style formatter (spaced
coordinates, blank lines between contours, trailing zero suppression)
- Fix empty Program tab when switching files while on the tab by
loading immediately instead of only marking stale
- Set contour-type colors on entities at load time and restore base
colors before selection highlight to prevent color bleed to CAD view

Wire up the Apply button to parse the G-code text back into a Program,
rebuild contours via ConvertProgram/ShapeBuilder/ContourInfo, and fire
ProgramChanged so callers receive the updated program.
