ssh: Ensure long server names (and nicknames) truncate (#19621)

Just polishing the UI a bit more. One drawback of this, though, is that
if you _do_ have a big nickname or server name, with this current
solution, you won't be able to see it. Ideally, we should be able to
hover over it and see it in a tooltip, but the `div` still doesn't
support that out of the box.
