Created Job that demonstrates how to access Stalwart admin API
via kubectl exec to modify security settings.
This Job shows the pattern for automated fixes but requires
knowing the exact API endpoints for Stalwart v0.16.11's
security configuration.
The Job must be manually triggered after determining the
correct API structure.
