Remove NavItemBlueprint in favor of page-based nav discovery

Drop the deprecated NavItemBlueprint from the public API and migrate core
plugins to set title and icon on PageBlueprint instead. AppNav keeps
backward compatibility for legacy nav-item extensions via an internal
core.nav-item.target data ref.

Removed the deprecated `NavItemBlueprint`. Navigation items are now discovered from page extensions via their `title` and `icon` params. The app nav extension still accepts legacy `nav-item` extensions for backward compatibility.
