Implement Compose dev profile screen

The DevProfileScreen(developerId) overload was an empty stub, so
play.google.com/store/apps/dev?id= deep links rendered a black screen.
Render the developer's stream bundle via the existing StreamCarousel,
observing DevProfileViewModel for loading, error/retry and per-cluster
pagination.
