REPLACES emergency disable with intelligent verification:
1. Position Identity Verification:
- Compares DB exitTime vs active trade timestamps
- Verifies size matches within 15% tolerance
- Verifies direction matches (long/short)
- Checks entry price matches within 2%
2. Grace Period Enforcement:
- 10-minute wait after DB exit before attempting close
- Allows Drift state propagation
3. Safety Checks:
- Cooldown (5 min) prevents retry loops
- Protection logging when position skipped
- Fail-open bias: when uncertain, do nothing
4. Test Coverage:
- 8 test scenarios covering active position protection
- Verified ghost closure tests
- Edge case handling tests
- Fail-open bias validation

User can now rely on automatic orphan cleanup without risk of
accidentally closing active positions. System protects newer trades
when old database records exist for same symbol.
