createPacketInteractionEntity

Creates a packet-only Interaction entity for click detection. This entity is invisible to players but receives their clicks. Should be called after the model is spawned. Props get a compact client-targetable interaction surface for entity-use input that Bukkit may not otherwise expose. Dynamic models deliberately stay on exact OBB air/block routing plus their backing-ID alias: a single axis-aligned square large enough to cover a long or rotated OBB would swallow unrelated clicks in its empty corners.
