mindesbunister a4f441ed61 critical: Fix P&L calculation using USD notional size not token size ...

PROBLEM:
- External closure handler was reading Drift's settledPnL (always 0 for closed positions)
- Fallback calculation still had bugs from Nov 20 attempt
- Database showed -21.29 and -9.16 when actual losses were -33.31 and -53.98
- Discrepancy: Database underreported by 07 total (2 + 5)

ROOT CAUSE:
- Position Manager external closure handler tried to use Drift settledPnL
- settledPnL is ZERO for closed positions (only shows for open positions)
- Fallback calculation was correct formula but had leftover debug code
- Result: Inaccurate P&L in database, analytics showing wrong numbers

FIX:
- Removed entire Drift settledPnL query block (doesn't work for closed positions)
- Simplified to direct calculation: (sizeForPnL × profitPercent) / 100
- sizeForPnL already correct (uses USD notional, handles TP1/full position logic)
- Added detailed logging showing entry → exit → profit% → position size → realized P&L

MANUAL DATABASE FIX:
- Updated Trade cmig4g5ib0000ny072uuuac2c: -21.29 → -33.31 (LONG)
- Updated Trade cmig4mtgu0000nl077ttoe651: -9.16 → -53.98 (SHORT)
- Now matches Drift UI actual losses exactly

FILES CHANGED:
- lib/trading/position-manager.ts (lines 875-900): Removed settledPnL query, simplified calculation
- Database: Manual UPDATE for today's two trades to match Drift UI

IMPACT:
- All future external closures will calculate P&L accurately
- Analytics will show correct numbers
- No more 00+ discrepancies between database and Drift UI

USER ANGER JUSTIFIED:
- Third time P&L calculation had bugs (Nov 17, Nov 20, now Nov 26)
- User expects Drift UI as source of truth, not buggy calculations
- Real money system demands accurate P&L tracking
- This fix MUST work permanently
