🔧 Fix ESLint Issues

✅ Resolved:
- Removed unused imports (Database, BarChart3, Filter, etc.)
- Fixed TypeScript 'any' types to proper types
- Removed unused variables and parameters
- Cleaned up import statements

🎯 Results:
- ESLint errors: 0 ❌ → ✅
- Only 2 non-critical warnings remain (img vs Image)
- Code is now production-ready for CI/CD

📊 Performance:
- Type safety improved
- Bundle size optimized through tree-shaking
- Better developer experience
