refactor: simplify BoardContainer and update task management

- Removed initialTasks and initialStats props from KanbanBoardContainer, now using TasksContext for task management.
- Updated useTasks hook to include a simulated delay for sync indicator during task updates.
- Replaced KanbanBoardContainer with HomePageClient in the HomePage component for a cleaner structure.
