Scan only M15 and H1; keep D1 as confirmation, drop W1 entirely

Trades are intraday (M15/H1) only. D1 stays as a confirmation TF
for both so higher-timeframe trend context still gates A/A+ grades.
W1 is no longer used anywhere — removes one batch call.

Scan now: 3 batch calls (M15, H1, D1) × 7 pairs = 21 credits, ~2 min.
Was:      4 batch calls (M15, H1, D1, W1) = 28 credits, ~3 min.
