fix: handle logged in logo visibility in landscape

previously the two logos were assigned to the same variable,
so toggling visibility on landscape mode hid one of the logos
(the login one) but did not hide the other one (logged in one)

now we maintain reference to both logos and toggle visibility
of both in landscape mode
