Add clickable server URL to dev mode port info output

[venmanyarun]

Fixes #528

When dev mode starts or the user presses 'p', print a clickable URL alongside each HTTP/HTTPS port line so users can navigate directly to the running server.

Screen Recording of new Port info
We can see that Host Openliberty server page link is coming as a clickable link when server is being started in dev mode.
Also if user presses "p" keyboard shortcut, port info is again displayed, which also contains local host URL

In container mode (devc), Liberty runs inside the container. The hostname Liberty binds to and reports in CWWKT0016I is the container's internal hostname or IP (e.g. 172.17.0.2) — which is only reachable from within the container network, not from the developer's machine.

What the developer actually accesses is localhost: — the port that Docker/Podman maps from the container to the host machine (e.g. -p 9080:9080). That mapped host port is what gets stored in httpPort via findLocalPort().

So for liberty:devc, the container URL will have localhost hardcoded

@venmanyarun Please add a screenshot of the new info. It is difficult to see/read in the video when pausing.

As discussed at the meeting today, let's go with Liberty welcome page: for the label. Also, since the developer owns the configuration where enableWelcomePage=false may have been set, we think it is ok to display the url even if it does not go to a valid page. It would give the developer an easy way to test that their configuration worked.
