fix: render desktop nav at all widths when no links, fix profile menu positioning

Skip mobile sidebar/hamburger entirely when no links snippet is provided.
The nav with .no-links class stays in desktop layout at all screen widths.
Override UserHeader mobile styles from .no-links context to keep dropdown
opening downward with tail centered below the profile picture.
