Kanban View Option for Akiflow

Introduce a Kanban view option in Akiflow, allowing users to switch from the standard calendar view to a more visual task management layout. This feature would enable users to organize tasks by stages, such as "To Do," "In Progress," and "Completed," providing a more intuitive, drag-and-drop experience for managing tasks. The Kanban view would be particularly useful for individuals managing multiple projects, helping them track progress and prioritize tasks more efficiently.
