implement Navigation 3 and Movie Details screen

- Update Android Gradle Plugin to 8.9.1 and target SDK to 36. - Integrate `androidx.navigation3` for Compose-based navigation management. - Implement a centralized `NavigationManager` and `Route` system (supporting `Home` and `Movie` routes). - Add a comprehensive Movie Details screen featuring hero images, synopsis, metadata chips, and cast lists. - Refactor `HomePage` and related components into a dedicated `hu.bbara.purefin.app.home` package. - Enhance `JellyfinApiClient` with methods to fetch item details and "next up" episodes. - Update `PurefinActivity` to use `NavDisplay` for handling app navigation and backstack. - Setup Hilt modules for providing navigation-related dependencies.
