Describe the bug
In the Enatega web app, when users attempt to add a restaurant or store to their favorites list, the action does not work. Clicking the favorite (heart) icon has no effect—the item is not added to the favorites section, and no visual confirmation or feedback is shown.

To Reproduce
Steps to reproduce the behavior:

Log in to the Enatega web app
Browse to any restaurant or store
Click the favorite (heart) icon
Observe that the item is not added to the favorites list
Expected behavior
Clicking the favorite icon should immediately add the selected store or restaurant to the user's favorites list, with appropriate UI feedback (e.g., filled heart icon, success message).
