feat(mobile-nav): enhance responsive sidebar with user info and auth actions

- Remove userRole prop, read user directly from auth store
- Add user info section (avatar, name, email) when logged in
- Add Masuk/Daftar buttons at bottom when unauthenticated
- Add Keluar button with loading state when authenticated
- Add tagline under logo in sidebar header
- Add backdrop blur effect for better visual depth
- Use flex-col layout for consistent spacing at any height
