feat: update Daily management features and enhance date handling

- Marked the calendar/history view of dailies as completed in the TODO list.
- Improved date formatting in `formatDateForAPI` to avoid timezone issues.
- Added `getDailyDates` method in `DailyClient` and `DailyService` to retrieve all dates with dailies.
- Enhanced `POST` route to robustly parse date input for better error handling.
- Integrated daily dates loading in `DailyPageClient` for calendar display.
