🧹 refactor(PageLayout): remove unused state variables

Removed unused `userState` and `statusState` bindings from `PageLayout.js`
while retaining their dispatch functions for authentication and status
management. Confirmed correct use of array destructuring to skip the
unused toggle function returned by `useSidebarCollapsed`.

This change introduces no functional differences and solely improves
readability and maintainability.
