Why does a ceiling fan not stop immediately when electric supply is cut off?

It has momentum and the rotor is free to keep turning in the motor. It slows gradually due to friction of the rotor and the blades moving through air. If there were no friction it would never stop. The bad part is that there would be no air either so you wouldn't care.
