fix(backoffice): wording quality pass across orders, moderation, transactions, users, customers

- Replaced hardcoded English audit/timeline text (order status changes,
  review moderation events, user role/status changes) with proper
  adminXxx.timelineEvent.*/adminUsers.audit.* i18n keys, so Recent
  Activity/Timeline/Audit panels no longer mix English into ru/hy UI.
- Translated raw internal codes rendered directly to users: transaction
  payment method ('card'/'qr'/'cash_on_delivery' -> adminTransactions.methodValue.*)
  and user roles/permissions ('products.manage' etc -> adminUsers.roleValue.*/
  adminUsers.permission.*), replacing developer-facing enum leakage with
  real copy.
- Fixed wrong-noun list-footer counts: Orders/Transactions/Moderation
  list pages all reused adminProducts.items ("N товаров"/"N products")
  regardless of what was actually listed; each now has its own itemsCount
  key ("N заказов", "N транзакций", "N отзывов").
- Fixed customer detail page's "Back" button reusing adminOrders.back
  ("Back to orders") instead of a customers-specific label.
- Added translation keys to en/ru/hy + translations.ts interface for all
  of the above.
