- Add ErrorBoundary component for React error handling
- Create animated error pages (403, 404, 500, 502, 503)
- Implement ErrorAnimation component with seven-segment display
- Add apiClient (axios) and apiFetch (fetch) wrappers with automatic error page redirects
- Migrate critical API calls to use new error handling
- Update font from Roboto to Open Sans across all components
- Remove unused CLIENT_URL from docker-compose files
- Rename 404Page.css to ErrorPage.css for consistency
- Add comprehensive ERROR_HANDLING.md documentation
- Created new modular components:
* ConsentManager: Manages workshop + social media consents with individual save
* GroupMetadataEditor: Manages group metadata (title, description, name, year) with save
* ImageDescriptionManager: Manages image descriptions with batch save
* DeleteGroupButton: Standalone group deletion component
- Refactored ManagementPortalPage to use modular components:
* Each component in Paper box with heading inside (not outside)
* HTML buttons with CSS classes (btn btn-success, btn btn-secondary)
* Inline feedback with Material-UI Alert instead of SweetAlert2 popups
* Icons: 💾 save, ↩ discard, 🗑️ delete
* Individual save/discard functionality per component
- Enhanced ConsentCheckboxes component:
* Added children prop for flexible composition
* Conditional heading for manage mode inside Paper box
- Fixed DescriptionInput:
* Removed duplicate heading (now only in parent component)
- React state management improvements:
* Deep copy pattern for nested objects/arrays
* Sorted array comparison for order-insensitive change detection
* Set-based comparison for detecting removed items
* Initialization guard to prevent useEffect overwrites
- Bug fixes:
* Fixed image reordering using existing /api/groups/:groupId/reorder route
* Fixed edit mode toggle with unsaved changes warning
* Fixed consent state updates with proper object references
* Fixed uploadImageBatch signature to use object destructuring
* Removed unnecessary /api/manage/:token/reorder route from backend
Next: Apply same modular pattern to MultiUploadPage and ModerationGroupImagesPage
