Remove or implement AdvancedOverrides.

AdvancedOverrides is accepted by the CRD, but applyUserDeploymentConfigs never reads it. Configured patches are silently ignored. If implemented, validate patch paths with an allow-list before applying them.

Apply DeploymentConfig.Replicas during deployment reconciliation.

The current applyUserDeploymentConfigs implementation does not read DeploymentConfigs.Replicas. Valid values therefore leave the generated Deployment replica count unchanged, and the documented leader-election behavior for ExternalSecretsCoreController never activates. Set deployment.Spec.Replicas from this field and preserve the default of 1 when the pointer is nil.
