fix(cli): resolve PR #1513 review blockers — fix actor add --update enforcement tests

Remove @tdd_expected_fail tags from actor_add_update_enforcement.feature and
fix step invocations to use the new positional NAME argument signature for
agents actor add. The fix for issue #1500 is already on master; these tests
were failing only because they used the old command signature (without NAME).
