fix: ensure regime columns exist before ML prediction

Browse Source 
When regime detection fails silently on first iteration, df lacks
regime/regime_confidence columns. XGBoost then gets 74 features
instead of 76 and throws feature_names mismatch error.

Fix: add default regime columns (regime=1, regime_confidence=1.0)
after regime detection block and in the fallback position-check path.
Also upgrade regime error logging from DEBUG to WARNING for visibility.
