[REQUEST]: Enable endpoint actions in events

[christineweng]

Description

Endpoint actions (isolate/release, respond) were available in alerts. This PR extends the availability to events. If a host can be isolated, it will show up for an event. 2 places where users expect to see updates:

• When investigating in analyzer (must be open in flyout), clicking an event opens an event preview, isolate host and respond are now available in take action
• When in event flyout (from host, user table), the options are also shown in the take action menu.
