Fix aircraft track propagation issues in web frontend
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. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
