Clean up excessive console logging and remove duplicate app files

- Remove verbose console.log statements from WebSocket, map, and aircraft managers
- Keep essential error messages and warnings for debugging
- Consolidate app-new.js into app.js to eliminate confusing duplicate files
- Update HTML reference to use clean app.js with incremented cache version
- Significantly reduce console noise for better user experience
