Template-Level Default for Hide Value and Disable Editing Setting

NetBrain currently requires users to manually enable the 'Hide value and disable editing for others' option on each change template individually, with no way to configure it as a default at the template level. This enhancement would allow administrators to set this option as a default behavior for a given change template, so it applies automatically without repeated manual configuration. This would reduce administrative overhead and help ensure consistent visibility and editing restrictions are applied across teams using the same template.
