make open dashboard an anchor, and close the preview-navigate verify

Four navigates were flagged; one was real. The two ProjectPreview lines are
void — Projects was deleted in July. Of the two in DashboardPreview, the
create path writes the dashboard and then goes there, which a link cannot
express, so it stays. The Open Dashboard button in the edit form was pure
navigation and is now a link.
