refactor: explicit imports instead of wildcards (S2208, batch_07) (#2044)

* refactor: replace wildcard imports with explicit ones (S2208, batch_07)

* Restore imports that the cadcraft batch dropped so the engine compiles

Explicit import lists missed names the files still use. Restore them and
the test-module globs.
