test(plugin-auth): the prelude pin's as-declared grant title is the person-named one

Semantic merge conflict with #24941's pin, resolved in one line. Its
direct-grant case "as declared" read the declared sys_user_permission_set
title as the raw user id, a precondition asserted before the count. On
this branch the declared title IS the one-hop person title, so both cases
of the pair now read 'Prelude → prelude_editor'. The counts the pin
holds (8 reads in 4 round trips) are unchanged and green.
