fix(seed): populate userId for UAT staff and SEED_ADMIN_EMAIL staff

GRO-666: resolveStaffMiddleware returns 403 for UAT users because
staff records have NULL userId after seed. This change populates
userId (and oidcSub) for all staff created via seedKnownUsers()
and the main seed path using the same value as the OIDC sub.
