Fix aircraft track propagation issues in web frontend

Browse source 
This commit addresses issue #23 where aircraft track changes were not
propagating properly to the web frontend. The fixes include:

**Server-side improvements:**
- Enhanced WebSocket broadcast reliability with timeout-based queueing
- Increased broadcast channel buffer size (1000 -> 2000)
- Improved error handling and connection management
- Added write timeouts to prevent slow clients from blocking updates
- Enhanced connection cleanup and ping/pong handling
- Added debug endpoint /api/debug/websocket for troubleshooting
- Relaxed position validation thresholds for better track acceptance

**Frontend improvements:**
- Enhanced WebSocket manager with exponential backoff reconnection
- Improved aircraft position update detection and logging
- Fixed position update logic to always propagate changes to map
- Better coordinate validation and error reporting
- Enhanced debugging with detailed console logging
- Fixed track rotation update thresholds and logic
- Improved marker lifecycle management and cleanup
- Better handling of edge cases in aircraft state transitions

**Key bug fixes:**
- Removed overly aggressive position change detection that blocked updates
- Fixed track rotation sensitivity (5° -> 10° threshold)
- Enhanced coordinate validation to handle null/undefined values
- Improved WebSocket message ordering and processing
- Fixed marker position updates to always propagate to Leaflet

These changes ensure reliable real-time aircraft tracking with proper
position, heading, and altitude updates across multiple data sources.
