Add pages to customer accounts

Merchants have diverse needs and some use cases won't fit into extension targets on existing customer account pages. For example, to create extensions for popular use cases like loyalty programs, wishlists, subscriptions, returns, and exchanges, a separate page is required. In these cases, build a full-page extension using the target. The full-page extension renders UI in a new page, below the header and above the footer.
