Issue 2: The application doesn't handle the onDragStart, onDragOver, onDrop, and onDragEnd events.

[sbmsr]

What you need to do

Implement handleTaskDragStart, handleTaskDragOver, handleTaskDrop, and handleTaskDragEnd to handle the drag-and-drop events.

The application currently does not handle these events, which are necessary for the drag and drop functionality of the tasks. They can be found between lines 24-48 of App.tsx.

Subtask 2.2

Make sure the application doesn't leave a lingering task when dragged over a column but dropped elsewhere.
