Module: ContainerPreview (#176)
Added ContainerPreview for showing shulker box and ender chest contents with locking feature to hover over containing items. Echest needs to be opened at least once in the session to show the contents. <img width="1513" height="979" alt="image" src="https://github.com/user-attachments/assets/1db2b381-e9a9-45c3-b367-5d2ba4188792" />
