Feat: Add drag and drop feature for file upload in "Upload Content" section

[saadgibawa]

Describe the feature

Currently, users can only select files via the "Choose File" button in the "Upload Content" section. To improve the user experience and make uploading more convenient, I propose adding a drag-and-drop feature that allows users to drag files directly into the upload area.
