EUR/USD A-grade signals had inverted quality curve (-1.65R) because all
trades got RR≈0.50 and mature_move logic penalized high-score entries.
Fix: add per-pair trade setup params (sl_atr_floor=1.2, min_rr=1.0,
mature_move_threshold=35) and apply quality_scale to both tp_mult and
min_rr so A-grade gets wider TP targets. Also wire EUR config into
backtest via PAIR_PRODUCERS registry.
Result: A-grade now +1.24R (was -1.65R), total EUR/USD +10.06R (was +4.20R).
XAU/USD unchanged at +13.01R.
