add refresh button for querying for new runs without completely reloading app

[gfrogat]

currently you have to reload the website to get new run and thereby loose the complete app state 😕

You mean, when adding new run JSON files to the backend, they should be available in the select2?

In the simplist case the refresh button can load the run list and replace it in the frontend. A more sophisticated option would be a websocket connect and receiving new runs via "push" event.
In my opinion we should keep it simple. ;-)

yes, querying the run endpoint and updating the select2 would be enough.

websockets would be nice for live-updates but we already iceboxed that idea some time ago.
