Support direct upload and card creation when dragging or pasting images onto the canvas

Is your feature request related to a problem? Please describe. Currently, when a user drags an image onto the canvas, the system does not automatically upload the image and create a new card. The user would like a feature that allows seamless image uploading and card generation through a drag-and-drop interaction. This would improve the user experience by making image insertion more convenient and streamlined.
