[FIX] web: user menu always shown by default (in community)

Before: the user menu would disapear when the screen was smaller than
some threshold. It is expected in enterprise, but not in community as
it doesn't have the burger menu.

After: The menu is set to always be displayed. To remove it becomes
an enterprise reponsability.
