Tune EUR/USD defaults: tighter SL, higher TP, A-grade filter, unblock ranging

Config changes from EUR/USD optimization rounds:
- sl_atr_multiplier 1.5→0.5, tp_atr_multiplier 1.0→1.5, min_rr 0.5→1.0
- Unblock ranging regime, restrict to A+/A quality on M15
- Lower entry thresholds: score 38→30, confidence 60→50
- Add M5-specific regime weights and config overrides in eurusd.py
