Replace the three ItemsControl sections (Overdue/Open/Completed) with a single flat Rows collection (HeaderRow | TaskRowViewModel) bound to a ListBox + VirtualizingStackPanel, so the realized container count stays bounded instead of growing with the list (measured: ~7-8 realized containers at any scroll position with 1000 source rows). Group headers become regular row entries, each section is simply omitted from Rows when empty, and the Completed section's Clear-completed action moves onto the header row itself. SectionFor/ReorderAsync/FindNextInSameSection now read a row's section off the nearest preceding HeaderRow in Rows instead of three separate bound collections, and ScrollSelectedIntoView goes through ListBox.ScrollIntoView so it still works for rows outside the realized window. Drag/reorder behavior, grouping/counts, and the Clear-completed button are unchanged. Auto-scroll-while-dragging and the cross-section reorder bug are explicitly out of scope (follow-up tasks).
