feat: Enhance flight trails with historical altitude data and fix label display

Browse source 
- Extend PositionPoint struct to include altitude field in position history
- Update position history population to store altitude with each position
- Fix 3D aircraft labels to show GroundSpeed instead of undefined Speed field
- Enable true 3D flight trails with proper altitude visualization
- Improve trail accuracy by using historical altitude data per position

Resolves trails showing flat paths and labels showing N/A for speed.
