Add Suppressed Alarms Count to Active tab

[slominskir]

Requested during ops review

Currently the Active tab creates a Server Sent Events connection on the effective-alarms topic, but filtered by initallyActiveOnly. To accommodate this request we may need to remove that server filter and perform client-side filtering. This may impact page performance, especially initial page load. The number of active alarms should be low in general, whereas loading all alarms (currently around 25 - 30,000) is much more costly in network load, server load, and page load time.

Also worth mentioning some Active alarms are "Incited", which could also be displayed in a separate count (though that is already part of the Active count).
