Advanced Predictions Module

Enhanced predictive features:
1. Form Momentum Tracking - From REAL API data
2. Head-to-Head Analysis - From REAL API data
3. League Position Factor - From REAL live standings
4. Market Odds Integration - Compare predictions to bookmaker odds
5. Confidence Calibration - Auto-adjust based on accuracy history
6. Multi-factor Ensemble - Combine all factors intelligently

NOTE: All data is now fetched from live APIs (Football-Data.org)
