feat: show server url by pressing u

[sapphi-red]

Description

#11228 implemented keyboard shortcuts. A shortcut to open the local server URL by the browser was implemented in that PR and could be considered as a solution of #10527. But I think there's cases when I want to open other URLs or in a non-default browser.

This PR implements a shortcut to show the server URLs. This way we can avoid the terminal to be narrow. The disadvantage of this approach is that additional two steps ("focusing the terminal" and "pressing u key") are required compared to #10527's suggested solution.

I think this is a good idea 👍🏼
About #10592, it would be interesting to provide more fine grained log levels or filtering. But I agree that this PR is a better alternative.

Would you add a line break when pressing u so the printed URLs are cleaner?
