fix: faces of an extrude drawn over a face's projected edges keep an exact source (#505)

A profile traced over a face sketch's projected boundary left the extrude's caps and sides without an exact planar source, so a sketch or offset plane on the new top face was refused. The drawn curve is now the edge's source where it covers a projection. Clearer fixed-plane message; regression tests in the engine, UI harness and design corpus, plus a corpus-wide flat-face attachment check (known gaps under #491-#495).

Fixes #489

The scripts that made them are in `scripts/` (`issue-489-stacked-join` was drawn in the desktop
app and has none). Every flat face of every final body must also take an attached sketch and an
offset plane; the faces that can't yet are listed with their issues in `design_corpus.rs`.
