Added missing icon types (heavy, large, light, medium) to the loadIcons() function.
The icon cache was only loading 6 out of 10 available SVG icons, causing aircraft
with weight-based classifications to display as plain circles instead of proper
aircraft icons.
Fixed icon types now loaded:
- ✅ commercial, helicopter, military, cargo, ga, ground (existing)
- ✅ heavy, large, light, medium (newly added)
This ensures all aircraft with known ADS-B emitter categories display the correct
type-specific icons instead of falling back to generic circle markers.
