Add nextCursor pagination to grid responses

- FTL: Capture Moqui pagination vars (pageIndex, pageSize, pageMaxIndex, listCount)
- Compact mode: Add nextCursor object with pageIndex, pageSize, hasMore
- ARIA mode: Add nextCursor to grid nodes
- Add totalCount to show full result size

Usage: Pass nextCursor values as parameters to get next page:
  parameters: {pageIndex: 1, pageSize: 20}

Response format:
  nextCursor: {pageIndex: 1, pageSize: 20, hasMore: true}
  totalCount: 29
