Improve image upload error handling and validation (#17188)

- Add URL validation in getImageBufferFromUrl utility
- Add response status validation and content-type checking
- Add timeout and connection error handling with specific error messages
- Validate buffer is not empty before processing
- Validate file type detection results before proceeding
- Ensure detected file type is actually an image format
- Add proper type safety for Axios error handling

This improves robustness when uploading images from URLs by:
- Preventing invalid URLs from being processed
- Providing clear error messages for different failure scenarios
- Ensuring only valid image files are processed
- Handling network errors gracefully
