fix: dashboard reload redirect

[Dmytro-Doronin]

Fixed private pages redirect after reload and added AuthIndicator to the mobile menu

[Copilot]

Pull request overview

This PR updates the client’s auth/role route guards to avoid incorrect redirects during session rehydration after a reload, and updates the mobile menu to show an authenticated user indicator.

Changes:

• Add auth initialization/loading handling to RequireAuth and RequireRole using authInitDone (and accessToken) to delay redirects until session bootstrap completes.
• Add a reusable ModalOverlay component and use it for full-screen loading states in RequireRole.
• Update the mobile menu to show ProfileIndicator when authenticated and adjust auth detection to include accessToken.
