feat(dashboard): breadcrumbs that follow how you reached a page

Browse Source 
Detail pages carry a breadcrumb bar built from a per-tab trail in
sessionStorage: following a link from a page on the trail extends it,
going back to one cuts it there, and opening a page directly shows its
natural parents. The property 3D view's back button goes to the previous
crumb, and the property page renames its crumb once its name loads.

/**
* Breadcrumbs that follow how you actually got to a page, kept per browser tab (sessionStorage).
* A detail page has <nav data-crumbs data-crumb-label="..."> holding its natural parents as links (what shows when
* the page is opened directly); every other page starts a new trail. Arriving from a page on the trail (by link
* or script, seen through the same-origin referrer) continues it from there; returning to a page on the trail
* (back, a crumb, reload) cuts it back to that page. Crumbs.label(text) renames the current page once its name
* has loaded. A link marked data-crumb-back points at the previous page on the trail.
