Refactor the monolithic MjLogsTable component (971 lines) into a modular,
maintainable architecture following the same pattern as LogsTable refactor.
## What Changed
### 🏗️ Architecture
- Split large single file into focused, single-responsibility components
- Introduced custom hook `useMjLogsData` for centralized state management
- Created dedicated column definitions file for better organization
- Implemented specialized modal components for Midjourney-specific features
### 📁 New Structure
```
web/src/components/table/mj-logs/
├── index.jsx # Main page component orchestrator
├── MjLogsTable.jsx # Pure table rendering component
├── MjLogsActions.jsx # Actions area (banner + compact mode)
├── MjLogsFilters.jsx # Search form component
├── MjLogsColumnDefs.js # Column definitions and renderers
└── modals/
├── ColumnSelectorModal.jsx # Column visibility settings
└── ContentModal.jsx # Content viewer (text + image preview)
web/src/hooks/mj-logs/
└── useMjLogsData.js # Custom hook for state & logic
```
### 🎯 Key Improvements
- **Maintainability**: Clear separation of concerns, easier to understand
- **Reusability**: Modular components can be reused independently
- **Performance**: Optimized with `useMemo` for column rendering
- **Testing**: Single-responsibility components easier to test
- **Developer Experience**: Better code organization and readability
### 🎨 Midjourney-Specific Features Preserved
- All task type rendering with icons (IMAGINE, UPSCALE, VARIATION, etc.)
- Status rendering with appropriate colors and icons
- Image preview functionality for generated artwork
- Progress indicators for task completion
- Admin-only columns for channel and submission results
- Banner notification system for callback settings
### 🔧 Technical Details
- Centralized all business logic in `useMjLogsData` custom hook
- Extracted comprehensive column definitions with Lucide React icons
- Split complex UI into focused components (table, actions, filters, modals)
- Maintained responsive design patterns for mobile compatibility
- Preserved admin permission handling for restricted features
### 🐛 Fixes
- Improved component prop passing patterns
- Enhanced type safety through better state management
- Optimized rendering performance with proper memoization
## Breaking Changes
None - all existing imports and functionality preserved.
