fix(ui): prevent NavMenu logo from overlapping hamburger on mobile

On viewports ≤768px the burger button is position:fixed at the
viewport edge, while the header retained its default 1rem left
padding. The logo image therefore sat completely underneath the
button, causing a visible overlap on hover.

Increase .nav-header padding-left to 3.75rem on mobile so the
.nav-brand clears the 2.5rem fixed toggle with a 0.5rem gap.

Bump version → 1.10.6
