ui-shared: Display path limit directly beneath tab bar in relevant pages

Design-wise, the path is shown by "expanding" the grey border between the
tab bar and the content area of the page to house the current path limit.

This is only displayed on pages where the path limit is relevant, and only
when a path limit is in effect.
