refactor: simplify CalendarPage and CalendarHeader components by removing unused props

- Removed the handleGoToToday function and its associated prop from CalendarPage, streamlining the component's logic.
- Eliminated the isLoading and onRefresh props from CalendarHeader, enhancing clarity and reducing complexity.
- Updated internationalization messages to remove references to "Today" and "Refresh," aligning with the component changes.
