test(cli): stop patching Path.stat with a 1-arg lambda in the FTS notice test

The salvaged #88217 test replaced Path.stat on the class with a lambda
taking one positional arg; pathlib.exists() passes follow_symlinks= and
pytest's own tmp_path teardown crashed with INTERNALERROR TypeError.
Delegate to the real stat for every path other than state.db.
