Add more information to connection detail UI

Add the following to the default UI for connection details:

* Proxy server URL
* AWS IAM auth enabled/disabled
* Region
* Service type
* Fetch timeout
* Neighbor expansion limit override

This will aid in diagnosing issues as the most intuitive thing for a user to do is to screenshot the connection screen where the error is displayed. So showing more information will avoid an unnecessary back and forth for more information about the connection.

## Possible solutions

We will have to mock up a few UI options to see what fits best.

Start by locating the default connection-detail UI in the React application and reviewing how connection settings are currently represented. Mock up and choose a layout that displays the proxy URL, AWS IAM auth state with region and service type, fetch timeout, and neighbor expansion limit override; done means these values are visible on the connection screen and the selected UI fits the existing design.
