Fix navigation bar wrapping on smaller screen sizes

[abbiesims]

Done

Adds the $breakpoint-large value to avoid the nav bar wrapping onto a new line on smaller screens. The nav bar now switches to mobile version at this new breakpoint instead.

QA

• Go to the demo
• Check the nav bar switches to mobile version rather than wrapping onto two lines on smaller screens
