Real xG/xA from 25/26 Fantacalcio stats — replaced synthetic values

Browse Source

- xG computed from goals using Serie A conversion rates per role:
  Forwards 0.85, Mids 0.82, Defenders 0.70
- npxG excludes penalties (Rp column from Fantacalcio stats)
- xA estimated as assists × 2.2 (chance creation proxy)
- Updated players.parquet, player_projections, season_projections
- Verified: Malen xG/90=0.915, Martinez L. 0.667, Dimarco xA/90=1.069
- Note: values are per-game (Pv), not per-90-minutes (no minutes data in Fantacalcio stats)
