Fix: Critical Position Manager monitoring issues

**Root Cause:** Position Manager didn't detect when on-chain TP/SL orders closed positions externally, causing endless error loops and stale position data.

**Issues Fixed:**
1. Position Manager now checks if on-chain position still exists before attempting to close
2. Detects external closures (by on-chain orders) and updates database accordingly
3. Determines likely exit reason based on price vs TP/SL levels
4. Automatically cancels leftover orders when position detected as closed
5. Analytics now properly shows stopped-out trades

**Technical Changes:**
- Added position existence check at start of checkTradeConditions()
- Calls DriftService.getPosition() to verify on-chain state
- Updates database with exitPrice, exitReason, realizedPnL when external closure detected
- Removes trade from monitoring after external closure
- Handles size mismatches for partial closes (TP1 hit externally)

**Database Fix:**
- Manually closed orphaned trade (stopped out 9 hours ago but still marked 'open')
- Calculated and set realizedPnL = -$12.00 for stopped-out SHORT position
- Analytics now shows 3 total trades instead of missing the SL exit

**Testing:**
- Bot starts cleanly with no error loops
- Position monitoring active with 0 trades (as expected)
- Analytics correctly shows stopped-out trade in statistics
