Based on Kyle's input, the UI needs a bread crumb at the top of the page to show the navigation path from the main entity page (e.g. search page) to the current page (e.g. details page).

For most entities the bread crumb should look like this:

- Main/search page: (empty)
- Details page: << Back to List >> (current entry's primary key)

Note that the settings and association tabs are considered a single details page, so the bread crumb doesn't change when switching tabs for the same entry.

For automount the bread crumb should look like this:

- Main page: (empty)
- Location page: << Back to Locations >> (current location)
- Map page: << Back to Locations >> (current location) >> (current map)
