Modified `getAdminUserCoupons` to accept an array of user IDs
and filter using `.in('user_id', userIds)` instead of executing
multiple individual `.eq('user_id', userId)` queries. This change
significantly reduces database calls and improves performance
when displaying admin dashboard data for multiple users. Backward
compatibility is maintained by supporting single ID strings.

💡 What: The
getAdminUserCouponsfunction inapp/actions/get-admin-users.tshas been updated to acceptuserId: string | string[]and now uses the Supabase.in('user_id', userIds)operator instead of.eq('user_id', userId). The function normalizes string inputs to arrays to maintain backward compatibility for existing callers.🎯 Why: To solve an N+1 query problem where fetching coupons for multiple users sequentially required a separate database query for each user. This change allows fetching all needed coupons in a single batched database query, significantly reducing the number of round trips, CPU cycles, and latency.
📊 Measured Improvement: A local benchmark simulated DB latency to demonstrate the theoretical difference between N queries and 1 batched query for 10 users:
