[giorgigordiashvili]

Summary

• Orders List (/pages/orders/list): TanStack React Table with 20 seed orders, clickable order ID links to detail page, customer name + email column, order date, total (formatted currency), payment status badges (Paid/Pending/Failed/Refunded), delivery status badges with icons (Delivered/Shipped/In Transit/Processing/Pending), search by customer name, payment status filter, column sorting, pagination, row selection, and delete action
• Order Details (/pages/orders/[id]): Dynamic route with 4-card grid layout:
  • Header Card: Order ID, date, payment + delivery status badges
  • Items Card: Product table with images, SKU, qty, prices + order summary (subtotal, shipping, tax, total) with ScrollArea for mobile
  • Customer Card: Name, email, phone, address with lucide icons
  • Timeline Card: Order status history using the existing Timeline component
  • Not Found: Fallback component for invalid order IDs

Localized links via ensureLocalizedPathname, RTL-safe with logical CSS properties. 15 new files, 20 seed orders with items and timeline events.

Test plan

• Navigate via sidebar: Pages > Orders > List
• Orders List: search customers, filter by payment status, sort, paginate, delete
• Click an order ID (e.g. #ORD-1001) — navigates to detail page
• Order Details: verify header badges, items table with summary math, customer info, timeline
• Navigate to /en/pages/orders/INVALID — shows "Order Not Found"
• "Back to Orders" link returns to list
• Sidebar: Orders > Details links to /pages/orders/ORD-1001
• RTL test at /ar/pages/orders/list and /ar/pages/orders/ORD-1001
