@Rekoo-PS reported the LanguageSelector pushing into the company-name
title on narrow viewports — the button always rendered
Globe + flag + full language name (~120px), and on mobile that pinched
the left-side title cluster in AdminHeader.
Wrap the name in `hidden sm:inline` so <sm the button collapses to
just Globe + flag, matching the existing "hidden xl:block" pattern
on the date display in the same header. Self-explanatory at icon-only
width (users see their current flag and a globe), and the dropdown
still shows full names when opened. Title/aria-label keep the name
discoverable for screen readers + tooltip hover on the icon-only state.
