Category Revenue with Relabeling
Rebrand product categories for a board presentation: Electronics → 'Tech Devices', Furniture → 'Workspace', all others keep their original name. For each renamed_category show: unique_products (COUNT DISTINCT), total_revenue (2 dec), avg_price (2 dec), completion_rate (% completed orders, 1 dec). Sort by total_revenue descending.
