🌟 Feature Overview
Implement a favorites/saved items feature that allows users to save products they are interested in. When a user clicks on the "Save" button for a product, it should be added to their profile under a "Saved Items" section. This will provide users with easy access to their favorite products when they are ready to check out.

🤔 Why this feature?
This feature enhances user experience by allowing customers to keep track of products they are interested in without having to search for them repeatedly. It simplifies the shopping process, making it easier for users to compile their final cart for checkout. By providing a "Saved Items" list, users can quickly refer to their favorites and make purchasing decisions more efficiently.

📋 Expected Behavior
Product Listing Update:
Each product card should include a "Save" button that allows users to add the item to their favorites.

User Profile Integration:
A "Saved Items" section should be added to the user profile, displaying all products the user has saved.
Users should be able to view, remove, or directly add saved items to their cart from this section.

Persistence:
The saved items should be persistent across sessions, meaning they will remain in the user's profile even after logging out and logging back in.

Notifications:
When an item is successfully saved or removed from favorites, a notification should inform the user of the action taken.
