Map the menu contract to view models

Project the menu contract object onto MVC view models for rendering. Trigger: OP-11 (build and attach the Business Online menu) step 3.

Field	Value
Operation ID	OP-13
Trigger	OP-11 (build and attach the Business Online menu) step 3
Inputs	BusinessOnlineMenu
Outputs	MenuViewModel with Favorites and Items
Primary components	Mappers.MapMenuViewModel(BusinessOnlineMenu)
Entry point	src/Web.Mvc/Classes/Mappers.cs

Steps

1. Project bolMenu.Favorites and bolMenu.Items through the private MapMenuItems, copying ApplicationName, FavoriteName, MenuCategory, MenuCategoryCode, PageId, PageLink, PageName, and Tooltip onto MenuItemViewModel.
2. The projection is a lazy Select with no materialization, so enumeration happens at render time.*
