revert: drop smartsheet backfill script from deploy

The script kept failing on deploy (ESM/CJS mismatch). User
opted to drop the auto-fix. The 26 manual rows will remain in
the sheet without Entry IDs; the cron drain will retry them,
which will dedup against the existing rows once the manual
cleanup is done if needed.
