WHY IT NEEDS A POLICY

Why set_spot_margin_auto_repay_mode needs a policy

This tool writes/modifies account settings (auto-repay mode for spot margin) but does not delete data or commit financial transactions directly. However, it has high severity because misconfiguration could lead to unintended automatic margin repayments, excessive fees, or forced liquidations if an AI agent sets this incorrectly without user intent.

From the tool's definition Tool name and description indicate 'Set spot margin auto repay mode' which modifies account margin settings. This is a reversible configuration change to the user's trading account that affects how margin interest is automatically repaid.
