Neo: Conductor draws browse blocks in the right column (#5883)

A browse block in a list page's right cell (e.g. a module's Featured block) became the cell's
endpoint, which the right column never renders, so the block was dropped. The right cell now
draws it as a block like any other; the top, centre and bottom cells still feed the list.
