Backoffice - breadcrumbs

## Is your feature request related to a problem? Please describe.
Loss of navigation context and relying on Browser Back button.

## Describe the solution you'd like
Breadcrumbs are implemented on the Frontsite, but Backoffice also needs same. Even on Frontsite, going back is non ideal - its similar to the Browser back which does a full refresh of Backed up page. It loses context and goes to the top of start search page. Ideally, if you are going back from the Detail page you'd like to go to the specific search results page and scroll region from which the selection was made. There are a few other issues that may also need to be addressed (such as multi-page skip-jump)

Start by locating the existing Frontsite breadcrumb implementation and the Backoffice detail and search navigation entry points. Clarify whether the first goal is breadcrumbs only or also preserving the originating search page and scroll position. Done should be defined as an agreed Backoffice navigation behavior, with the related navigation cases verified.
