Enhance article photo handling and API documentation.

- Updated API documentation to reflect changes in article data structure.
- Improved ArticlePhoto component to support dynamic sizing and object fit options.
- Added performance logging for image upload in ArticlePhotosDialog and ArticlePhotoTile components.
- Enhanced ArticleTile to conditionally render photos and adjusted styling for better layout.
- Optimized image preparation process with configurable AVIF encoding speed.
