- Fix zero coordinate handling to distinguish between invalid coordinates and valid 0.0 (equator/prime meridian)
- Add to_float_safe() function that preserves nil for proper coordinate validation
- Add comprehensive coordinate validation with descriptive logging in JavaScript
- Make position change threshold configurable via application config (default: 0.001°)
- Add extensive test coverage for edge cases including nil coordinates and equator crossing
- Improve robustness for real-world APRS coordinate edge cases

- Hide loading spinner after map initialization to prevent flash on updates
- Add position change detection logic with proper nil/Decimal handling
