Preresize images before storing them

[kof]

As a user I don't want to care about the size of the images I upload, webstudio should take care of that.

Reported bug:

Try to upload any image with a big resolution, e.g. 9800px. It will start uploading in asset manager, then show erorred/broken thumb.

I can see this in the response

What we can do

• Preresize the image if it has too large dimensions or too big file size before storing it in our storage
• This will also ensure optimium speed on image resizer because it can take too much time on first render if the image is too big
• additionally for lightbox type of use cases, we should probably have 2 types of images:
  • under 2k for general usage for fast resizing
  • 4k for large views like lightbox, if the original allows

we need to check why CF resizer showing this error and catch it before they do ourselves to show user a meaningful error
