NavigationProvider class

The NavigationProvider class is responsible for managing navigation-related state across the app. This includes handling top menu navigation, back navigation, and providing the appropriate AppBar title and navigation destination based on the user's interaction.

The provider listens for changes and updates the UI accordingly when the user navigates between screens or selects different menu items.
