WHY IT NEEDS A POLICY

Why reset_credit_note_to_open needs a policy

This tool modifies the status of a credit note by resetting it to 'open'. This is a reversible state change (Write), not a deletion or financial transaction. However, changing a credit note's status could have downstream accounting implications. The action can be reversed by changing the status again, so it does not qualify as Destructive.
