Detailed Description

Hosts a temporary QLineEdit directly on the canvas to rename an element's label in place, in response to GraphicElement::inlineEditRequested().

Follows the SceneDropHandler/ConnectionManager pattern: holds a back-reference to the owning Scene and delegates the undo command back to it. Only one inline edit is ever active at a time; starting a new one commits whatever was already in progress.
