feat: integrate task creation functionality in HomePageClient and Kanban components

- Added task creation modal in HomePageClient with state management for visibility.
- Implemented `handleCreateTask` function to handle task submissions.
- Updated Kanban components to accept `onCreateTask` prop for task creation, ensuring consistent task management across the application.
- Removed unused task creation UI elements from Kanban components to streamline the interface.
