Treat missing archived cells as active rows

When a CSV adds an archived column but older/active rows omit the trailing field, csv.DictReader supplies None for that cell, so this .strip() raises AttributeError before any rows are checked. That makes the new archived-row support fragile for partially backfilled CSVs; coerce the value with something like (row.get("archived") or "") so omitted flags remain active rows.
