Add 'Clear Manual Closes' button to analytics

- New button in analytics page to clear orphaned trades
- API endpoint /api/trading/clear-manual-closes
- Intelligently checks Drift positions before deleting
- Only removes trades with no matching position or mismatched entry price
- Safe operation: keeps trades on error (false positives better than deletions)
- User-friendly confirmation dialog
