Fixes incorrect time calculations in the interface clocks:
UTC Clock Issues Fixed:
- Remove incorrect timezone offset addition that was causing wrong UTC display
- Use proper getUTCHours() and getUTCMinutes() methods directly on current time
- Ensure UTC clock shows actual UTC time for aviation coordination
Last Update Clock Issues Fixed:
- Stop using UTC methods for local "last update" time display
- Use getHours() and getMinutes() for proper local time representation
- Last update clock now shows meaningful local time when data was received
Technical Changes:
- Add useUTC parameter to updateClock() method for proper time zone handling
- Simplify time calculations by using appropriate Date methods
- Add clear comments explaining clock behavior and timezone usage
Expected Behavior:
- UTC clock displays current UTC time (aviation standard)
- Last update clock displays local time of most recent data update

Resolves issue #3 where aircraft age field was always showing 0 seconds.
Backend Changes:
- Fix MarshalJSON in merger.go to calculate age dynamically using time.Since(a.LastUpdate)
- Add comprehensive tests for age calculation in merger_test.go
Frontend Changes:
- Add calculateAge() utility method to both aircraft-manager.js and ui-manager.js
- Update popup content and aircraft table to use client-side age calculation
- Implement real-time age updates every second in app.js
- Add updateOpenPopupAges() function to refresh popup displays
Key Benefits:
- Aircraft age now shows actual seconds since last transmission
- Real-time updates in UI without requiring new WebSocket data
- Proper data staleness indicators for aviation tracking
- No additional server load - client-side calculation using last_update timestamp

Resolves#30
- Add comprehensive squawk code lookup database with emergency, standard, military, and special codes
- Implement squawk.Database with 20+ common transponder codes including:
* Emergency codes: 7700 (General Emergency), 7600 (Radio Failure), 7500 (Hijacking)
* Standard codes: 1200/7000 (VFR), operational codes by region
* Special codes: 1277 (SAR), 1255 (Fire Fighting), military codes
- Add SquawkDescription field to Aircraft struct and JSON marshaling
- Integrate squawk database into merger for automatic description population
- Update frontend with color-coded squawk display and tooltips:
* Red for emergency codes with warning symbols
* Orange for special operations
* Gray for military codes
* Green for standard operational codes
- Add comprehensive test coverage for squawk lookup functionality
Features:
- Visual emergency code identification for safety
- Educational descriptions for aviation enthusiasts
- Configurable lookup system for regional variations
- Hover tooltips with full code explanations
- Graceful fallback for unknown codes

Track and display the number of active WebSocket connections viewing the
aircraft tracker. Features:
Backend:
- Add getActiveClientCount() method for thread-safe client counting
- Include active_clients count in all statistics responses
- Integrate with existing stats API endpoints
Frontend:
- Display "X viewer(s)" in header stats with proper plural/singular grammar
- Add "Active Viewers" card to Statistics view
- Real-time updates as clients connect/disconnect
- Fallback to 1 when stats not yet available
This adds a social element showing "Now being watched by X users" style
information prominently in the interface.

Root cause: The merger was blocking position updates from the same source
after the first position was established, designed for multi-source scenarios
but preventing single-source position updates.
Changes:
- Refactor JavaScript into modular architecture (WebSocketManager, AircraftManager, MapManager, UIManager)
- Add CPR coordinate validation to prevent invalid latitude/longitude values
- Fix merger to allow position updates from same source for moving aircraft
- Add comprehensive coordinate bounds checking in CPR decoder
- Update HTML to use new modular JavaScript with cache busting
- Add WebSocket debug logging to track data flow
Technical details:
- CPR decoder now validates coordinates within ±90° latitude, ±180° longitude
- Merger allows updates when currentBest == sourceID (same source continuous updates)
- JavaScript modules provide better separation of concerns and debugging
- WebSocket properly transmits updated aircraft coordinates to frontend
