fix(kopiaui): fixed '<starting up>' in the tray menu. (#2813)

The fix is to use `127.0.0.1` instead of `localhost` when starting the
server and polling for the server status.

This resolves an issue where KopiaUI can't connect to the server
which only listens on IPv4 localhost (127.0.0.1) but the Javascript
client prefers IPv6 (::1) and fails to connect.
