Critical fixes:
- Remove ensure_default_user() — no more auto-creating user with
password123. Login page now shows "Create Password" form on first
boot. User sets their own password during onboarding flow.
- CSRF 403: increased retry delay from 300ms to 500ms for stale
cookie recovery after remember-me session restore.
- Reboot: multiple fallback methods (/sbin/reboot, sysrq, kill init)
when USB is pulled and /usr/sbin isn't available.
