Updated MAC Core admin navigation with Helpers tab

Property	Value
description	Split utility controls into a dedicated `Helpers` tab without changing the stored option shape.
version	1.0.0
type	Update
related	Admin, Settings, Utils

• Split the utility toggles into a dedicated Helpers admin tab instead of leaving them mixed into the main Settings tab.
• Kept Settings, Helpers, License, and Support as the shipped top-level MAC Core admin views for 1.0.0.
• Kept the existing mac_core_settings['utils'] storage shape intact even though the admin IA changed.
• Preserved the existing upgrade path by avoiding a settings migration for the tab split.
