- Added `date-fns` as a dependency in `package.json` and `package-lock.json`.
- Refactored `Home` component to `HomePage`, implementing server-side rendering for tasks and stats retrieval.
- Integrated `Header` and `KanbanBoard` components for improved UI structure.
- Marked Kanban components as completed in `TODO.md`.
