Add coefficient extraction and variance-ratio controls to MorphologicalDeviationSc

[nawazishkhan1-nk]

Summary

This PR extends MorphologicalDeviationScore with coefficient access and exposes the functionality thru Python.

Changes Made

• Added GetPCACoefficients(const Eigen::MatrixXd& X) to project samples onto the fitted PCA basis and return the coefficient matrix.

• Added public retained-variance controls, to better allow manual variance control in MophoDevScoring:

  • SetRetainedVarianceRatio(double ratio)
  • GetRetainedVarianceRatio() const

• Added Python bindings for:

  • GetPCACoefficients
  • SetRetainedVarianceRatio
  • GetRetainedVarianceRatio

• Testing

  • Python binding tested manually by importing the module and calling the new methods on test set.
  • No new automated tests added.
