Refactor MenusContext and Runner class constructors

- Updated MenusContext to initialize _restaurantId inline.
- Fixed typo in Program.cs method name from AddAddtionalCardsAsync to AddAdditionalCardsAsync.
- Refactored Runner class to use constructor parameters directly.
- Replaced private _menusContext field with menusContext parameter in relevant methods.
