test: authenticated admin E2E tour with smart mock backend (all pages screenshot)

- Rewrote e2e/mock-backend.mjs to return valid auth responses (login + refresh)
- Created e2e/authenticated-tour.spec.ts that logs in and screenshots all 7 admin pages
- Fixed (dashboard-layout)/layout.tsx: added missing NextIntlClientProvider
- All pages render error-free in dark mode with mock data
- Screenshots: dashboard, members, distributions, distribution/new, stock, stock/new, reports
