ui: traffic-control edit: make network edit a single text field

here's to note that the radio-group was my idea, Dominik just
executed it, nicely that is.

But, the panel looks a bit glitchy layout wise as with that and the
bandwidth fields (maybe we should render their unit inline) the
vertical alignments were all over the place.

So for now make it a simple text field and throw in a tooltip for
good measurement
