[BUG] MWOCTRL cluster returns wrong status and improperly checks power level when not a valid power step increment

[rbultman]

Reproduction steps

1. Build and run the microwave oven example app.
2. Commission the app using chip tool.
3. Attempt to set the power level to 25.
   Result: The response from the app is INVALID_COMMAND instead of CONSTRAINT_ERROR.

Additionally, the check for a valid power step increment is incorrect. The existing check is:

newPowerLevel % PowerStep == 0

But it should be:

(newPowerLevel - MinPowerLevel) % PowerStep == 0

Bug prevalence

It fails the in-flight test case because it doesn't return the proper response.
