Use typed kwargs in CopperMountain M5xxx parameter subclasses

Update FrequencySweepMagPhase, PointMagPhase, and PointIQ to use
Unpack[ParameterBaseKWArgs] with concrete CopperMountainM5xxx instrument
type, extracting instrument via kwargs.get() + assert for label building
before super().__init__().
