Enatega Customer App: Don't display any restaurant on app with No products, categories etc

Is your feature request related to a problem? Please describe.
Restaurants that have no products, categories, or menu items configured are still visible to users in the app. These restaurants appear in listings and search results but contain no usable content, leading to a confusing and empty experience for the user.

Steps to Reproduce:

In the Admin panel, create or locate a restaurant with no products, categories, or menu items assigned.
Open the app and browse the restaurant listings or search for that restaurant.
Tap on the restaurant to view details.
Expected Result:
Restaurants with no products or categories should not be displayed in the app until they are fully configured with menu items.

Impact:

Poor user experience due to encountering unusable restaurant profiles
Wasted time and frustration for users
Potential decrease in trust in app content quality

Inizia dagli elenchi dei ristoranti e dal flusso di ricerca dell’app per i clienti, quindi traccia il modo in cui vengono caricati i dettagli dei ristoranti configurati senza prodotti, categorie o elementi del menu. Riproduci il caso del ristorante vuoto dal Admin panel e verifica che tali ristoranti non compaiano più negli elenchi o nei risultati di ricerca, mentre i ristoranti configurati rimangano visibili.
