Fix: Check inventory with quantity and product ID

[seer-by-sentry]

Fixes REACT-5WA. The issue was that: Backend hasInventory function hardcoded to return false, causing "Not enough inventory" error and subsequent 500 response.

• Implemented a check to ensure sufficient inventory based on the requested quantity of each product.
• Modified hasInventory function to accept productId, requestedQuantity, and inventoryList as parameters.
• Updated the inventory check to use the product ID and requested quantity to determine if there is enough stock.
• Added product ID to the error message when there is not enough inventory.
