* [Refactor] Move card item creation out of game logic * [Game] Rename signal to createCardRequested per review * [Game] Move attachment bookkeeping onto CardState CardState::setAttachedTo now maintains the attachedCards graph, resets the grid point and emits the zone events itself, so game logic no longer needs to reach into the CardItem graphics item. CardItem::setAttachedTo delegates to the state and keeps only the view teardown (deleteLater). --------- Co-authored-by: Lukas Brübach <Bruebach.Lukas@bdosecurity.de>
