Tommaso BianchiandClaude Opus 5 b305e8b154 tests: compile the five CAD test files that were never wired 
tests/libslic3r/CMakeLists.txt added only test_caddocument.cpp under
SLIC3R_CAD. The other five shipped in the tree and were never compiled, so
49 TEST_CASE blocks looked like coverage and were not: sketch constraints,
sketch editing, sketch import, inference, and the libslvs constraint set.

They also still targeted Catch2 v2 — mainline is on v3, where the umbrella
header is catch2/catch_all.hpp and Approx lives in the Catch namespace rather
than at global scope. Both fixed; nothing else in the files changed.

Found by building the tree rather than reading it. Suite goes from 374 to 423
test cases, 54,424 to 54,620 assertions, all passing.
