Two follow-up polish items for drag-and-nest:
1. Cancelling the "Extract from team?" dialog now snaps the
dragged card back to where the drag started. Before, a user
who dragged a child out, saw the confirm dialog, then clicked
Cancel ended up with the card stranded outside the parent at
its drop-point position — which also got persisted via
savePosition on drag-stop. Now onNodeDragStart captures the
pre-drag position + parent, and cancelNest restores both the
RF node position and fires savePosition with the absolute
pre-drag coords so reload matches.
2. Un-nesting now clears the ex-parent's explicit width/height
in the nodes array. growParentsToFitChildren is grow-only so
it could never shrink the parent back down after a child
left; the card stayed at its auto-grown size with empty
space. Stripping width/height lets React Flow re-measure from
the card's own min-width / min-height CSS, so the parent
visually shrinks to fit whatever children remain.
923 canvas tests pass.
