The `Vault` contract allows an admin to transfer ERC20 and ERC1155 tokens from the contract's balance. It includes functions for transferring a specified amount of ERC20 tokens and both single and batch transfers of ERC1155 tokens to a designated address. The contract ensures that only an admin can execute these token transfers, leveraging the `Auth` and `ERC1155TokenReceiver` functionalities.
