Subject: [PATCH 1/2] Refactor ExpandableCalendar header layout measurement
 logic

- Introduced a ref to conditionally measure header height only when necessary.
- Updated onHeaderLayout to prevent unnecessary state updates.
- Adjusted onLayout prop for Animated.View to utilize the new measurement logic.
