ui: access: revert icon swap, use realm over auth.

Moving icons around is not to ideal for people accustomed to the old
ones, at least if they are used for a new component on the same view.

Rather use the address-book icon, which is also used for adding a new
realm in PVE, we can rather switch over PVE to that and the text
"Realms", as that is also the label one sees when logging in, so a
better fit to keep that consistent.
