Projects imported via CSV that lack a target_year were invisible in Capital
Planning because findForPlanning() filtered on target_year IS NOT NULL. This
removes that filter and adds an "Unscheduled" Kanban column (orange background,
2-col layout) so users can drag unscheduled projects into year buckets.
Also bumps app version to 2026.3.2 (beta).
