fix(nav): desktop 'More' was clipped; mobile menu never listed Marketplace

- Desktop: the nav's overflow-x-auto clips its trailing item when the nav grows,
  which is exactly the 'More' menu. Widened the header (max-w-[1700px] vs the
  1400px page container), tightened nav padding to px-3 and nowrap. 'More' is
  fully visible at 1280/1440/2000px with Marketplace pinned (was missing).
- Mobile: the burger menu hard-coded only Map/Lab/Events/Crews + a few extras, so
  Marketplace (and Mints) were unreachable. It now appends every nav-catalog item
  not already listed, giving mobile/desktop parity (Marketplace, Mints, …).
