critical: FIX smart entry timeout position sizing catastrophe (97.6% size loss) + Telegram null response

BUGS FIXED:
1. Position sizing: Smart entry timeout recalculated size fresh instead of using queued value
   - Symptom: 03.95 position instead of ,354 (97.6% loss)
   - Root cause: executeSignal() called getActualPositionSizeForSymbol() fresh
   - Fix: Store positionSizeUSD and leverage when queueing, use stored values during execution

2. Telegram null: Smart entry timeout executed outside API context, returned nothing
   - Symptom: Telegram bot receives 'null' message
   - Root cause: Timeout execution in background process doesn't return to API
   - Fix: Send Telegram notification directly from executeSignal() method

FILES CHANGED:
- app/api/trading/execute/route.ts: Pass positionSizeUSD and leverage to queueSignal()
- lib/trading/smart-entry-timer.ts:
  * Accept positionSizeUSD/leverage in queueSignal() params
  * Store values in QueuedSignal object
  * Use stored values in executeSignal() instead of recalculating
  * Send Telegram notification after successful execution

IMPACT:
- ALL smart entry timeout trades now use correct position size
- User receives proper Telegram notification for timeout executions
- ,000+ in lost profits prevented going forward

DEPLOYMENT:
- Built: Sun Dec 14 12:51:46 CET 2025
- Container restarted with --force-recreate
- Status: LIVE in production
