Activate window only (no toggle) when inbound connection arrives

## PR Checklist
* [x] Closes #10386
* [x] I work here
* [x] Manual test passed.

## Detailed Description of the Pull Request / Additional comments
The default for the `SummonWindowBehavior` is a toggle of the visibility state. I didn't realize that. We do not want that for inbound connections. We want always-brought-to-front.

## Validation Steps Performed
- Made the change. Launched Terminal as default as active window. Runbox'd another command. It didn't hide itself like it used to. Stays visible.
