Wire Queue demo seeder to shared DemoWorld

Org name, branches, ticket customers, and staff Members now come from
DemoWorld so Queue continuity matches Care/Frontdesk across the suite.
Also resolve organization by owner_ref when metadata.queue.organization_id
is missing, and skip reseed-on-login for DemoWorld staff emails.
