4H Trend Logic Added

The signal engine now checks the 4H trend alongside 5m, 15m, and 1h.

This upgrade improves signal accuracy and helps define how long to hold a trade:

✅ If 4H trend aligns → signals are stronger and can be held 4–8 hours (swing-friendly)

⚠️ If 4H contradicts → signal still shows, but marked as short-term (15–60 mins scalp)
