fix(nav): even out the profile menu row spacing

The Theme sub-trigger inherited the shared sub-trigger padding (py-1.5,
no min-height) while every sibling row carries min-h-11 py-2, so the
Theme row sat a few pixels shorter and the menu read as unevenly spaced.
Match the item height on this instance only, leaving other dropdowns'
sub-triggers untouched.
