Add Opportunities/Conference Scout track card, handle empty subtask lists

Currently no open items, just a note about the manual monthly sync step
(next run 2026-09-01). Also hardens buildTaskDetail/buildTaskSidebarCard
for entries with zero subtasks: shows "No open items right now" instead of
an empty table, and "No open items" instead of a misleading "All done" in
the sidebar summary chip.
