feat: add toggle all functionality for daily checkboxes

- Implemented `toggleAllToday` and `toggleAllYesterday` methods in `useDaily` for batch checkbox state management.
- Updated `DailySection` to include a button for toggling all checkboxes, enhancing user interaction.
- Integrated new toggle functions in `DailyPageClient` to support the updated checkbox handling.
