fix: admin sidebar missing on /admin/my-menu page

Rename loadMenuConfig() → loadUserMenuConfig() in adminMyMenuConfig()
to avoid shadowing the sidebar's loadMenuConfig() inherited from data()
via the spread operator. The name collision caused the sidebar to never
populate its menuData, showing only the fallback "Dashboard" link.

-// TODO: BUG - Sidebar menu doesn't update immediately after changes.
-// User must navigate to another page to see the updated menu.
-// The issue is that Alpine.js doesn't properly track reactivity for the
-// visibleMenuItems Set in init-alpine.js. Attempted fixes with reloadSidebarMenu()
-// and window.location.reload() didn't work reliably.
-// Possible solutions:
-// 1. Convert visibleMenuItems from Set to plain object for better Alpine reactivity
-// 2. Use Alpine.store() for shared state between components
-// 3. Dispatch a custom event that the sidebar listens for
-// 4. Force re-render of sidebar component after changes
+// NOTE: The page method for loading user menu config is named loadUserMenuConfig()
+// (not loadMenuConfig()) to avoid shadowing the sidebar's loadMenuConfig() inherited
+// from data() via the spread operator. Shadowing caused the sidebar to never populate
+// its menuData, resulting in a blank sidebar on this page.
