Major Fix Summary:
- Position Manager was tracking wrong entry price after orphaned position restoration
- Used stale database value ($141.51) instead of Drift's actual entry ($141.31)
- 0.14% difference in stop loss placement - could mean profit vs loss difference
- Startup validation now queries Drift SDK for authoritative entry price
Impact: Critical for accurate P&L tracking and stop loss placement
Prevention: Always prefer on-chain data over cached DB values for trading params
