The origin of this, I think, was nuclear weapons. The existence of nuclear weapons, and particularly ICBM nukes, created an existential military threat which Congress would never be able to act on in time, and so some shift in war-making authority had to be transferred to the presidency out of dire necessity, though that never seems to have been properly handled by constitutional clarification.
I agree that nukes were part of it, but I think Vietnam was the main impetus for the War Powers Act.
As for "constitutional clarification", the law itself invoked the "necessary and proper" clause (as being necessary and proper to providing for the common defense, one of the enumerated powers of Congress).
