feat: add initial pending tasks support in DailyPage

- Updated `DailyPageClient` to accept and pass `initialPendingTasks` to the `PendingTasksSection`.
- Modified `page.tsx` to fetch pending tasks from the service and handle graceful fallbacks.
- Adjusted `PendingTasksSection` to initialize state with `initialPendingTasks` and prevent unnecessary loading when initial data is present.
