Render events on route pages

[razor-x]

How to map event to route pages? Events looks like acs_system. so we could match all events for the resources on the route page (see #300 (comment)).

But then we have lock.unlocked and there is no lock resource. Ideally we can annotate events with yaml metadata in the front matter to include the namespace or better route` where it is relevant.

Let's wait for #305 since this should setup a pattern we can use here.
