Design tab: GUI for 15 tools that only had an MCP method

Browse Source

Every CAD feature added across M1-M8 got a kernel API and an MCP method, and
almost none got a card. The MCP path was the only way to reach them, so from
the Design tab these features did not exist: add_axis and add_coordsys have
been callable since M1 with no UI at all.

Wired here, in three batches:

  datum    Axis (5 construction types), CoordSys
  surface  Surface Extrude / Revolve / Loft / Fill / Offset / Thicken Surface
  body     Transform, Mirror, Thicken, Rib, Project, Delete Face, Helix

Grouped into existing dropdowns rather than widening the 16-slot toolbar:
surfaces get one new "Surface" dropdown, body ops join Dress-up, Thicken/Rib
join Add-material, Helix joins Datum (renamed "Datum / Curve"). Shift+Y and
Shift+Z went to Transform and Mirror; the remaining five are shortcut-less
rather than getting invented chords.

Three places where the UI has to encode a kernel distinction, not just expose
a field:

- Surface Offset and Thicken Surface consume a SHEET body and fail with "target
  is not a sheet" on a solid, so their pickers filter on
  CadDocument::is_sheet_shape() and say so when no sheet exists. Thicken (solid
  face -> plate) is a different tool and is kept visibly separate.
- delete_faces is a vector, so Delete Face accumulates picks via "Add picked
  face" and shows the running list. Supporting one face would have been a
  silent downgrade of the kernel field.
- CoordSys labels its edge pick with the consequence of omitting it: without an
  edge, datum_frame() takes x from coordsys_x_hint (world constant) and the
  frame cannot express rotation about its own normal — which is snaporca-en4,
  and is why a Fastened mate built on a face-only connector cannot fix spin.

The Rib sketch picker needed the 3-arg Append(text, wxNullBitmap, clientdata):
ComboBox's own Append(text, bitmap) hides wxItemContainer's (text, void*), so
the 2-arg call resolves to the bitmap overload and fails with "conversion from
void* to const wxBitmap is ambiguous". The Sweep picker already documents this;
Rib now matches it.

Compiles clean (0 errors) against snaporca-deps; kernel suite unchanged at
139 cases / 1960 assertions. Mate, the interference report and the M6 variables
panel are still to come; the GUI itself has not been exercised on a display yet.
