Summary

Updated three AWS managed policies: added ListInvestigations action, changed to wildcard permissions, added AWS Organizations permissions, and removed MFA conditions

The addition of wildcard permissions and new AWS Organizations permissions expands access. These changes directly impact security posture and access control.
