Major Frontend Refactoring:
- Replace ImagePreviewGallery with unified ImageGallery/ImageGalleryCard components
  - Support 4 display modes: group, moderation, preview, single-image
  - Add hidePreview prop to conditionally hide group preview images
  - Unified grid layout with responsive 3/2/1 column design

- Remove 15+ legacy files and components
  - Delete UploadedImagePage, SocialMedia components, old upload components
  - Remove unused CSS files (GroupCard.css, Image.css/scss)
  - Clean up /upload/:image_url route from App.js

- Fix image preview functionality in MultiUploadPage
  - Convert File objects to blob URLs with URL.createObjectURL()
  - Add proper memory cleanup with URL.revokeObjectURL()

- Improve page navigation and layout
  - Fix GroupsOverviewPage to route to /groups/:groupId detail page
  - Adjust PublicGroupImagesPage spacing and layout
  - Fix ModerationGroupsPage duplicate stats section

CSS Refactoring:
- Rename GroupCard.css → ImageGallery.css with updated class names
- Maintain backward compatibility with legacy class names
- Fix grid stretching with fixed 3-column layout

Development Environment:
- Add docker-compose.override.yml for local development
- Create Dockerfile.dev with hot-reload support
- Add start-dev.sh and nginx.dev.conf
- Update README.dev.md with development setup instructions

Production Build:
- Fix frontend/Dockerfile multi-stage build (as → AS)
- Update prod.sh to explicitly use docker-compose.yml (ignore override)
- Resolve node:18-alpine image corruption issue
- Backend Dockerfile improvements for Node 14 compatibility

Documentation:
- Update TODO.md marking completed frontend tasks
- Clean up docs/images directory
- Update README.md with current project status

All changes tested and verified in both development and production environments.
