- Add backend/locale/ar_SA/LC_MESSAGES/django.po with Arabic (ar-sa) translations
for all 62 user-facing error/validation strings across accounts, bookings,
payments, and notifications apps; compile to django.mo
- Add common.loading and salon.unknownStaff keys to both ar-sa.json and en.json
- ProtectedRoute: replace hardcoded "Loading..." with t("common.loading")
- BookPage, SalonDetailPage: replace `Staff ${s.id}` fallback with
t("salon.unknownStaff", { id: s.id })
- BookingsPage: pass getActiveLocale() to toLocaleString so date/time
format matches the active app language
All 35 backend tests and 7 frontend tests pass.

Implemented localization foundations across backend and frontend (locale settings/middleware, preferred language, i18n wiring, RTL support, minimal Arabic UI strings, Accept-Language).
Added targeted backend and frontend tests plus a risks note for pending full translation coverage.
