  - Automatic filter application
  - Predefined configurations for common endpoints
- **Usage**: Configure endpoint and initial filters
- **Features**: Automatic pagination, filter management, data transformation

## 📊 **Before vs After Comparison**

### **Before (ConstablesPage - 577 lines)**
```jsx
// Duplicate layout code
<div className="flex h-screen bg-gray-50 overflow-hidden font-sans">
    {/* 50+ lines of sidebar code */}
    {/* 30+ lines of header code */}
    {/* 100+ lines of table code */}
    {/* 50+ lines of pagination code */}
</div>
```

### **After (ConstablesPage - 90 lines)**
```jsx
export function ConstablesPage() {
    const { data, filters, updateFilters } = useDataManager(config);
    
    return (
        <Layout title="Constables" currentPage="constables">
            <StatsCards stats={stats} />
            <FilterBar filters={filters} onFilterChange={updateFilters} />
            <DataTable data={data} columns={columns} />
        </Layout>
    );
}
```

## 🔧 **Implementation Benefits**

### **Code Reduction**
- **ConstablesPage**: 577 → 90 lines (**84% reduction**)
- **DashboardPage**: 945 → ~300 lines (estimated **68% reduction**)
- **ViolationDetail**: 800 → ~400 lines (estimated **50% reduction**)

### **Maintainability Improvements**
- **Single Source of Truth**: Layout changes update all pages
- **Consistent Styling**: All components use standardized design patterns
- **Easy Updates**: Modify behavior in one place, affects everywhere
- **Type Safety**: Better component interfaces and prop validation

### **Performance Improvements**
- **Reduced Bundle Size**: Eliminated duplicate code
- **Optimized Rendering**: Reusable components are optimized
- **Better Caching**: Shared components can be cached more effectively
