Summary

Implements comprehensive transponder code (squawk) lookup and textual descriptions as requested in issue #30. This enhancement significantly improves the aviation utility of SkyView by providing immediate recognition of emergency situations and educational context for transponder codes.

🚨 Safety Features

Emergency Code Recognition

7700: General Emergency - Red highlighting with ⚠️ warning symbol
7600: Radio Failure - Immediate visual identification
7500: Hijacking/Unlawful Interference - Critical safety alert

Emergency codes are prominently displayed with red backgrounds and bold text for instant recognition by users.

✈️ Aviation Database

Comprehensive Code Coverage

Standard VFR Codes: 1200 (US/Canada), 7000 (ICAO/Europe)
Special Operations: 1277 (Search & Rescue), 1255 (Fire Fighting)
Military Codes: 0000 (No Transponder), 4000-4777 (Low Altitude), 0100-0777 (Interceptor)
Operational Codes: 1000 (Mode A/C), 2000 (Uncontrolled Airspace), 7001 (EU Conspicuity)

Regional Support

US/Canada specific codes (1200, 1201, 1202, 1255, 1277)
