Capital Planning: show beyond-window projects in Future bucket, 2-col layout

Projects with target years beyond the 5-year planning window now
appear in the Future column of the Kanban board (previously they
were invisible). Cards for these projects show their specific target
year as a badge. The Future column uses a 2-column grid layout when
it has more than 3 projects to maximize screen utilization.
