The drag-end relied on the row TouchArea's pointer-up, which only arrives
if the row still holds the grab. Inside a ListView (or a Flickable that
stays interactive) the scroll gesture can steal the grab mid-drag, so the
up never reached the row and the ghost stayed glued to the cursor. Add a
`changed pressed` safety net that ends the drag on any release or grab
cancel (both paths guard on ta.dragging, so end() runs once). Also give
LabelPageView's Flickable the interactive: !DragState.active flag the
other track views already have.
