Tommaso Bianchi 2b02a8e3dd Design tab: move the CAD sources into their own folder
Review request on PR #15238: "Place CAD-related files (e.g. CadDocument/
GeometryEngine) into a separate folder."

  src/libslic3r/CAD/     the kernel — CadDocument, GeometryEngine, the four
                         Sketch* units, SketchSolver, ThreadStandards
  src/slic3r/GUI/CAD/    the tab — DesignPanel, DesignCanvas, DesignSketchTool,
                         SketchInlineEditor, McpControl, generated DesignOffer

Pure relocation: no line of logic changes. Two include rewrites follow from it —
files that moved re-spell their own neighbours against src/ (already on the
include path), and files that did not move pick up the new folder. docs and
docs/ux/mockups/gen_offer_table.py follow the same paths.

Verified: libslic3r, libslic3r_gui and libslic3r_tests all build, CAD suite green
at 2518 assertions in 194 test cases, and the sibling fork builds identically —
17 shared sources still byte-identical, 8 diverging by their expected counts.
