Subject: [PATCH] fix(webrichtexteditor): add image drag-and-drop validation

- Implement MIME type checking to only accept image files (jpg, png, bmp)
- Add URL validation logic to filter valid image formats during drag operations
- Update dragEnterEvent and dragMoveEvent handlers to properly handle
  image file validation before accepting proposed actions
- Prevent non-image files from being processed in the rich text editor
