IKEv2 is much more common than IKEv1 these days so the "Mode" column is nearly always blank since it's irrelevant to IKEv2.

We can make this column share between authentication and mode, that way it's showing something much more interesting for all tunnels and will still continue to show a mode for older IKEv1 tunnels.

While here, the Mobile P1 is labeled "Mobile Client" in the list which seems to imply it is a client and not for clients. Pluralize that to be consistent with all the other usage in the GUI.
