The Location column rendered City/State only, so a vendor whose location lives
in the free-text address field showed an em dash while the detail drawer, which
already composes address with city, state and zip, showed the value.
Carry address through the list item type and mapper, which previously dropped
it, and fall back to it in the Location cell when City/State are blank.
Structured City/State still wins when both are present.
