Begin laying framework for Threat Monitoring UI

Part of [WAF statistics reporting][1].

This sets up some of the frontend framework for the Threat Monitoring
page, including a basic store and the root app component.

As this feature is not yet complete, it is disabled by default behind
the `threat_monitoring` feature flag.
