fix(quickadapter): restrict CatBoost grow_policy for Ordered boosting

CatBoost's Ordered boosting mode only supports SymmetricTree grow policy.
When Optuna suggested Ordered boosting with Depthwise or Lossguide grow
policies, CatBoost raised: "Ordered boosting is not supported for
nonsymmetric trees."

This fix conditionally restricts grow_policy options to SymmetricTree when
boosting_type is Ordered, preventing invalid parameter combinations during
hyperparameter optimization.
