Improve the error checking mechanism for the ChestShopSign metadata…

… handling by introducing a validation layer. This layer will delay the metadata saving task, allowing the system to verify its correctness before execution, hence improving data integrity. The async task is scheduled with a one tick delay to ensure a smoother operation even under potential exceptions.
