Alarm favorite link URL does not have AddRefreshHeader-30 applied

When at least one alarm favorite filter is saved, the Status -> Alarms page contains a list of links to each of these favorites. The URLs for these links point to /alarm/list rather than /alarm/list.htm, so they do not get the AddRefreshHeader-30 filter applied to them in web.xml.

We should update these links to use /alarm/list.htm, or if that's somehow infeasible, add  an AddRefreshHeader-30 filter in web.xml to /alarm/list.

The event browser may have a similar problem since the two are implemented similarly.
