fix(webui): sp4, an organization's own task board with no filter on no longer says its tasks match the filters (#1873, lane sp4)

The scope's org= in the workspace read is where the board reads, not a filter, so the
count line and the empty state no longer treat it as one. Found in the retaken shots.
