- Duplicated validation logic
- Inconsistent UI patterns
- Scattered error handling
- Different loading states
- Varied navigation patterns

### **Solution Implemented**
**EntityForm Component**: A unified form infrastructure providing:

```typescript
interface EntityFormProps {
  mode: 'create' | 'edit';
  entityName: string;
  entityNamePlural: string;
  backUrl: string;
  listUrl: string;
  title: string;
  description: string;
  icon: React.ComponentType;
  form: UseFormReturn<any>;
  onSubmit: (data: any) => Promise<void>;
  isSubmitting: boolean;
  error: string | null;
  onDelete?: () => Promise<void>;
  isDeleting?: boolean;
  sidebar: React.ReactNode;
  children: React.ReactNode;
}
```

### **Key Features**
- **Consistent Layout**: 2/3 main form + 1/3 sidebar across all entities
- **Standard Navigation**: Unified breadcrumbs, back buttons, and redirect patterns
- **Error Handling**: Centralized error display and user feedback
- **Loading States**: Consistent spinners and disabled states during operations
- **Context Awareness**: Forms adapt based on current study/experiment context
