fix(admin): truncate and copy the login-overview IP address

A long IPv6 in the login overview forced the table to scroll sideways and
the full address was awkward to lift out. Cap the cell, ellipsize the
address, and make it a button that copies the full value to the clipboard
with a transient checkmark and a toast — keyboard-activatable, with an
accessible label. The empty case stays plain text.
