pos-rich-link and other emitters of pod-os:link should always trigger some kind of navigation #152
Description
Currently if PodOS emits a pod-os:link event nothing happens, if no pos-router is on the page to catch it and trigger a navigation. This leads to e.g. pos-rich-link to do nothing on custom dashboards, which is confusing, since it looks like a regular link.
There should always be a fallback, if no other component like pos-router reacts to the link event. E.g.. pos-app could catch it and trigger a normal browser navigation
