Miggo AIRoot Cause Analysis

The commit diff shows the function signature changed from MakeEmailPrimary() to MakeEmailPrimary(), with added UID validation. Before patch, there was no check that email.UID matches the requesting user's ID, enabling unauthorized primary email changes. This matches CWE-281's improper permission preservation description.
