Enable BUY-only chart patterns on M5 — bearish patterns dropped (OOS negative)

M5 factory: cp_enabled=True, patterns limited to inv_hs, double_bottom,
bull_flag. SELL CP lost -3.21R on OOS; BUY CP: +41.8R PF 1.60 on 12mo,
+65.2R PF 1.48 on 5yr. Adds +22R to the M5 book (708 vs 513 trades).
M15/H1 remain disabled — all failed OOS validation.
