Fix image CORS violations with comprehensive proxy and component updates

- Applied transformImageUrlForCors to all image-displaying components
- Added followRedirects: true to image proxy to serve actual content
- Proxy now returns 200 OK with image data instead of 301 redirects
- Maintains CORS headers required for SharedArrayBuffer support
- Added debug logging for proxy response monitoring

Resolves all image loading failures in development environment.
