Allow rows per page size selection to include 500 and 1000 (or configurable)

## Request
- Add support for larger "Rows Per Page" options in table/grid UIs (e.g., 500 and 1000), in addition to the current options (10, 25, 50, 100).
- This is useful for scenarios with batch jobs processing hundreds of instances.
- The feature should make larger sizes available in the dropdown, and also allow one to set a larger default page size, not just via filters.
- Ideally, the set of page sizes are configurable to meet individual application's needs.

## Motivation
- Currently, when working with large datasets, exporting requires paging through many result pages.
- Providing larger page size options significantly improves the export and batch review workflows.
