Fix image resizing Lambda function - resolve variable errors and

[ImBIOS]

Summary

Fixed critical bugs in the image resizing Lambda function that were preventing resized images from being created and displayed properly.

Issues Fixed

1. Variable name error: Fixed undefined resized_path variable in download_and_resize function (line 61)
2. Duplicate upload: Removed redundant upload operation that was happening twice
3. Missing parameter: Added target_bucket parameter to download_and_resize function
4. Poor error handling: Improved handling of non-image files to prevent unnecessary uploads

Testing

• Verified image files are properly resized and uploaded to the resized bucket
• Confirmed non-image files are skipped without attempting resize operations
• Tested that the web interface now correctly displays both original and resized images with proper file sizes

Before/After

Before: Resized images showed "(bytes)" without actual file sizes in the web interface After: Resized images display proper file sizes and are accessible via presigned URLs
