fix: fetch updates on the detail page when change events are received

[gashcrumb]

for ENTESB-11405

@claudio4j this is what I was thinking in regards to the server events.

Looking deeper I think I led you astray a bit, useConnection returns a read() function that can be used to trigger a fetch, so another option would have been to call read() after calling the save function. But this approach should work as well, after going through the oauth dance once there's a change made to the connection the UI should then fetch an updated connection.

I can't seem to fully see this working in development mode though, it seems like the dev proxy isn't receiving the change events for some reason. Can you test this in your environment? You'd want to build the console and deploy it to verify I think, open the network tab and you should see a GET occur shortly after the ui does that PUT.
