- isOperator()/EnsureAdmin/broadcast fall back to is_admin so a legacy admin is
never locked out by a stale permission cache
- published modal: centered max-w-lg card (dynamic modalWidth class was purged
by Tailwind → full-width)
- datacenter edit moved to a modal (no row-height jump); location is now a
country dropdown (config/countries.php) instead of free text
