Efremenko Arhip a7e949a0a7 feat(users): bootstrap first admin on startup
BOOTSTRAP_ADMIN_EMAIL/PASSWORD seed a role=admin account at boot if absent —
the only way to get the first admin, since /register makes plain users and
promotion needs an existing admin. Idempotent and race-safe. Tests included.
