EMERGENCY FIX: Restore working map by removing broken ES6 module imports

🚨 Critical Issues Fixed:
- Removed broken ES6 import statements that caused map to freeze
- Restored traditional script loading in map.html
- Fixed map tree loading with working batch mechanism
- Temporarily disabled background data service to prevent module errors

🐛 Root Problems Identified:
- Mixed ES6 modules + traditional scripts don't work without proper setup
- Import statements were breaking JavaScript execution
- Background loading was working but map couldn't render trees
- Module loading paradigm was inconsistent across the app

✅ Map Now Works:
- Trees load and display properly with clustering
- Spiderfy spiral view restored and functional
- Proper zoom levels maintained (15 initial, 17 max)
- All clustering behavior preserved

⚠️ Technical Debt:
- Background data service code still exists but disabled
- Need proper module architecture for future optimization
- Authentication works, tree loading works, map functional
