{# alerts/list.html — the Alerts page (#5315): the verdict and what is active
   (alerts/_active.html, polled), then every rule: what it is doing now and
   when it last fired, what it fires on, and its History and Disable. The
   whole row opens the rule (.row-link, its name is the link); deleting one is
   on its own page, behind the confirm dialog. A rule covering hosts (#5464)
   lists its per-host rules under it, closed behind its "N hosts" toggle
   unless one of them isn't quiet (#5483); each opens its history. #}
