- Add imageUtils.js helper with getImageSrc() and getGroupPreviewSrc()
- Update ImageGalleryCard to use preview images for galleries
- Update ModerationGroupsPage to show preview images in modal
- Update ModerationGroupImagesPage to use preview images
- Update PublicGroupImagesPage to pass all image fields
- SlideshowPage continues using original images (full quality)
- Update nginx.dev.conf with /api/previews and /api/download routes
- Update start-dev.sh to generate correct nginx config
- Fix GroupRepository.getAllGroupsWithModerationInfo() to return full image data
- Remove obsolete version from docker-compose.override.yml
- Update TODO.md: mark frontend cleanup as completed

Performance: Gallery load times reduced by ~96% (100KB vs 3MB per image)
