[UI] [menu] remove menu height resizing

Remove the page action overflow and user menu height sizing. Previously,
a maximum menu height was set so that the menu itself would scroll. A
minimum height was also used so that the menu couldn't be shrunk down to
a silly size. Both the minimum height LESS and maximum height JS are now
removed.
