feat: add "Move to Today" functionality for pending tasks

- Implemented a new button in the `PendingTasksSection` to move unchecked tasks to today's date.
- Created `moveCheckboxToToday` action in `daily.ts` to handle the logic for moving tasks.
- Updated `DailyPageClient` and `PendingTasksSection` to integrate the new functionality and refresh the daily view after moving tasks.
- Marked the feature as completed in `TODO.md`.
