test(plugin-auth): type the seed-equivalence store's rows as rows

The store double stamps each row with its organization, and the spread
narrowed the inferred element type to that one key, so the retired-read
oracle's `.body` access failed check:test-typecheck (TS2339). Annotating
the array as `Row[]` restores the row type; the double's behaviour is
unchanged.
