WHY IT NEEDS A POLICY

Why set_emode_category needs a policy

This tool modifies the user's lending/borrowing configuration on a DeFi protocol by changing their E-Mode category, which affects their borrowing power. This is a reversible state change (Write), but carries high severity because misconfiguration could expose the user to liquidation risk by enabling higher leverage on correlated assets.

From the tool's definition Enter a High-Efficiency Mode (E-Mode) category to get higher borrowing power for correlated assets
