Detailed Description

Regression test: SCH_ITEM::SwapItemData must not change group membership.

When a design block (group) move is undone or canceled, each changed item's data is restored with SCH_ITEM::SwapItemData against a saved copy. That copy carries the item's data but no group pointer, so swapping m_group used to null the live item's group, leaving it orphaned from the group that still listed it as a member. The wire then behaved as a loose item and the block could tear apart on a later move.

Group membership is structural and is restored on its own (SCH_GROUP::swapData and the undo group-pointer pass), so a plain data swap must leave it untouched.
