feat: remove TaskStats from HomePageClient and Header components

- Eliminated `initialStats` prop from `HomePageClient` and `KanbanPageClient` to streamline data handling.
- Updated `Header` and `HeaderContainer` components to remove references to `stats`, enhancing clarity and reducing unnecessary complexity.
- Adjusted `useTasks` hook to make `stats` optional, ensuring compatibility with the updated components.
