critical: Fix P&L compounding bug in 25 historical trades

- Identified 25 trades with corrupted P&L from compounding bug
- Recalculated correct P&L for all affected trades (7 days)
- Total corrections: 63.23 in fake profits removed
- Today's actual P&L: -.97 (11 trades) - was showing -9.87 before fixes
- Last 7 days actual P&L: +7.04 (70 trades) - was showing +27.90

Bug pattern:
- P&L updated multiple times during close verification wait
- Each update added to previous value instead of replacing
- Worst case: -8.17 stored vs -.77 actual (7× compounding)

Root cause: Common Pitfall #48 - closingInProgress flag fix deployed
Nov 16 18:26 UTC but damage already done to historical data

Files modified:
- Database: 25 trades updated via SQL recalculation
- Fixed trades from Nov 10-16 with ABS(stored - calculated) > $1
