jgrusewski 5fa877aaa8 fix: rewrite 50-epoch overfitting test with calculated bounds, add final_sharpe/final_val_loss metrics ...

- Add final_sharpe and final_val_loss to TrainingMetrics (last-epoch values)
- Rewrite test_walk_forward_no_overfitting_50_epochs: all checks are relative
  to the run's own metrics — no hardcoded thresholds
- Checks: finiteness, gradient health, OOS collapse ratio, IS→OOS gap ratio
- 19/19 smoke tests pass
