feat: Extend smart validation timeout from 10 to 30 minutes

- Problem: Quality 70 signal with strong ADX 29.7 hit TP1 after 30+ minutes
- Analysis: 3/10 blocked signals hit TP1, most moves develop after 15-30 min
- Solution: Extended entryWindowMinutes from 10 → 30 minutes
- Expected impact: Catch more profitable moves like today's signal
- Missed opportunity: $22.10 profit at 10x leverage (0.41% move)

Files changed:
- lib/trading/smart-validation-queue.ts: Line 105 (10 → 30 min)
- lib/notifications/telegram.ts: Updated expiry message

Trade-off: May hold losing signals slightly longer, but -0.4% drawdown
limit provides protection. Data shows most TP1 hits occur after 15-30min.
