Implement pagination for members reports and update UI components

- Added a new `setPagination` action to manage pagination state in the members reports slice.
- Updated the members reports page to display the total number of members in the header.
- Enhanced the members reports table to handle pagination changes, ensuring data is fetched correctly based on the current page and page size.
