Download Execution Xlsx

Stream the Excel workbook for an execution.

For kind="list" reports rows are paginated through openpyxl's write-only mode so build memory stays constant; final ZIP buffer is sent in one chunk. Rows are capped at XLSX_MAX_ROWS because nothing can be sent until the workbook is complete — truncated sheets say so in their first row. Aggregate/top_n use the simpler render-then-send path.
