Image upload UI enhancements - Webfactory

We’ve made some improvements to the image upload experience when adding things like department and articles images:

• Smarter Loading Message: The “processing, please wait” message now waits for the image to actually finish processing, not just a timer so you're no longer stuck waiting too long (or not long enough).
• Faster Workflow: After uploading, you’ll now go straight to the final step where you can add the image, no more unnecessary stops at the rotate step.
• Simpler Crop/Rotate Tools: When cropping or rotating, you’ll now see just what you need: an "Apply" button and a back button. Other buttons like "Add Image" and "Cancel" will be hidden until they're relevant.
• Cleaner Warnings: The message about auto-cropping has been shortened to be clearer and less intrusive.

These updates only apply to image uploads like department images, not images added to page elements.
