What transfer_erc1155 does on SEI MCP Server V2

WHY IT NEEDS A POLICY

Why transfer_erc1155 needs a policy

This tool moves ERC1155 tokens from one address to another on the blockchain. While it is a write operation (modifying token balances), it is effectively irreversible in practice since blockchain transfers cannot be undone without the recipient's cooperation. However, it doesn't permanently destroy data (tokens still exist at destination), so Write is the most accurate category.
