Detailed Description

Base class providing a unique integer identifier for circuit items.

Every graphic element and connection inherits from ItemWithId to obtain a stable numeric ID managed by the owning Scene. IDs start as -1 (unassigned) and are set to a positive value when the item is added to a Scene via Scene::addItem(). The ID is used for undo/redo serialization and cross-reference during load/save.

Also self-unregisters from whichever SceneItemRegistry it is currently registered with, on ANY destruction path — including Qt's own parent-child cascade-delete, which bypasses Scene::removeItem's override. This structurally prevents a stale id->item registry entry from ever outliving the item (the WIREDPANDA-HC bug family).
