- Store track history with position, altitude, speed, and timestamp
- Automatic track point collection every 30 seconds when position changes
- API endpoint /api/aircraft/{hex}/history for individual aircraft tracks
- Frontend "Show History" button to display historical flight paths
- Click aircraft markers to show their historical track (dashed red line)
- Track cleanup: keep last 200 points per aircraft, 24-hour retention
- Add aircraft type badges in table view with color coding
- Start/end markers for historical tracks with timestamps
