## Summary
Closes#42402
- **Root Cause 1 (Row deduplication):** `DataTable`'s `getRowId` used
`row.id` directly as the react-table row identity. When query results
contain an `id` column with non-unique values (e.g., `SELECT id FROM
processes` where multiple hosts share PID 0), react-table deduplicates
rows with the same row ID, displaying fewer results than expected.
- **Root Cause 2 (Misleading count):** The "Showing X results" count was
derived from react-table's `rows` array, which was already deduplicated.
Fixing Root Cause 1 resolves this as well — all rows are now preserved,
so the count is accurate.
## Changes
- **`DataTable.tsx`**: Changed `getRowId` to append the array index to
the row ID (`${row.id}-${index}` instead of `String(row.id)`),
guaranteeing uniqueness while preserving the `id` prefix.
- **`InstallSoftwareTable.tsx`**: Updated `generateSelectedRows` to
produce keys matching the new `getRowId` format
(`${software.id}-${index}`), so that `defaultSelectedRows` continues to
correctly persist row selection.
## QA
1. Run a live query like `SELECT id FROM processes` targeting multiple
hosts → all rows should appear (no deduplication).
2. Verify the results count matches the actual number of displayed rows.
3. Verify the Setup Experience > Install Software table still correctly
shows pre-selected software with checkmarks persisted across pagination.
