CAD: a project whose model is a recipe is not an empty file

Browse Source 
Reopening a saved CAD design ended on a modal "The file does not contain any
geometry data." warning. A CAD project legitimately carries no mesh — the model
lives in the feature tree (Metadata/SnapOrca_cad.bin) until Commit to Plate — so
the warning is false for one, and it is the last thing the user sees after
opening a design they spent an hour on. It reads as "your work is gone" at the
exact moment the recipe HAS just loaded and the Design tab is about to rehydrate
it, and the main window sits disabled behind the dialog until it is dismissed.

Counts a non-empty model.cad_recipe as geometry.

Verified on the rig: save without Commit to Plate, reopen, and the Design tab
comes up with Sketch1 -> Extrude2 -> Body 1 editable, with no dialog at all.
