Smart Handling of Draft and Out-of-Stock Products in Link Products

REQUEST_SUMMARY_V2 Problem - Current System: The current 'Link Products' feature allows products to be connected with posts regardless of their stock status or if they are in draft, leading to situations where customers are shown products that are not available for purchase. Suggested Improvement: Update the 'Link Products' feature to exclude products in draft from being linked to posts. For products that are out of stock, automatically include an 'Out of Stock' mention when they are connected to a post. This approach ensures that customers are only shown available products or are clearly informed about the stock status, improving transparency and customer satisfaction.
