Low Stock Alert

What: On the Product form, add a "Minimum Stock Level" field. If, after a sale, the stock Quantity of a product falls below this level, the system generates a notification.

How: It can start with a "toast" notification on the frontend for the person who made the sale. In the future, this could evolve into an alert icon in the sidebar, a widget on the dashboard ("Low Stock Products"), or even an email. The backend already has the stock update logic; we just need to add an if statement.

Value: It transforms the system from reactive (the user discovers that the stock is low) to proactive (the system notifies them to buy more), preventing lost sales.
