feat: Complete Smart Entry Validation System with Telegram notifications

Implementation:
- Smart validation queue monitors quality 50-89 signals
- Block & Watch strategy: queue → validate → enter if confirmed
- Validation thresholds: LONG +0.3% confirms / -0.4% abandons
- Validation thresholds: SHORT -0.3% confirms / +0.4% abandons
- Monitoring: Every 30 seconds for 10 minute window
- Auto-execution via API when price confirms direction

Telegram Notifications:
- ⏰ Queued: Alert when signal enters validation queue
- ✅ Confirmed: Alert when price validates entry (with slippage)
- ❌ Abandoned: Alert when price invalidates (saved from loser)
- ⏱️ Expired: Alert when 10min window passes without confirmation
- ✅ Executed: Alert when validated trade opens (with delay time)

Files:
- lib/trading/smart-validation-queue.ts (NEW - 460+ lines)
- lib/notifications/telegram.ts (added sendValidationNotification)
- app/api/trading/check-risk/route.ts (await async addSignal)

Integration:
- check-risk endpoint already queues signals (lines 433-452)
- Startup initialization already exists
- Market data cache provides 1-min price updates

Expected Impact:
- Recover 77% of moves from quality 50-89 false negatives
- Example: +1.79% move → entry at +0.41% → capture +1.38%
- Protect from weak signals that fail validation
- User visibility into validation activity via Telegram

Status: READY FOR DEPLOYMENT
