The editor currently only supports copying and pasting images from the internet. It cannot paste images from the local clipboard, like screenshots. This PR adds support for pasting images directly from the clipboard.

@Darginec05 I've created this PR as a draft. I have a few questions I need your help with:

1. What's the best way to create a block for the pasted image? Currently, I’ve implemented it in a basic manner for the POC.
2. How can we extend this to allow users to upload the pasted image to their servers if needed?
   • Should we handle the uploading functionality in a separate PR to keep this one focused, or include it here?
