If you don't power a stepper motor it will spin freely with the only resistance being friction and the magnetic interaction between the rotor and the poles.

You could use a DC motor, but if it's a gear motor then you will have substantial resistance freewheeling because of the gear reduction.

Three things come to mind that would work:

  1. A sprag sprocket like on a bicycle or a sprag clutch

  2. A DC gear motor with an electrical clutch to completely disconnect the motor.

  3. A racheting mechanism. This might be the most practical since you can pick up really cheap 1/4" rachet tools and you could modify the head of one of them to drive a cable. Depends on how mechanically handy you are I guess, but it should work.
