Users can now choose how many records to display per page in the MassData grid (100, 1,000, 10,000, 100,000, or all). The backend and API client are updated to support nullable skip/take parameters, allowing "all" records to be fetched when desired. The pager and page count calculations are updated to reflect the selected page size, and the pager is hidden if only one page exists. Additional UI and CSS changes provide a combo box for page size selection. The API controller now treats take <= 0 as "no limit."
