Default food item added to the cart by default

Description:
When accessing the cart, a default food item is automatically added without any user action. This behavior can lead to confusion or incorrect orders.

To Reproduce

Open the application.
Navigate to the cart section.
Observe the presence of a default food item already added to the cart.
Expected behavior
The cart should be empty by default unless the user explicitly adds an item.

Actual Behaviour
A default food item is pre-added to the cart automatically, even when the user has not selected anything.

Desktop (please complete the following information):

OS: Windows
Browser: Chrome
Smartphone (please complete the following information):

Device: iPhone15pro
OS: iOS17.6.1

Start by reproducing the issue in the cart on Chrome and iOS, then trace where the cart is initialized and where its items are loaded. The work is done when opening a new cart leaves it empty until the user explicitly adds a food item, with the relevant behavior covered by the project's existing checks if available.
