Refactor: Extract RootScreen from MainActivity and fix reply message user

This commit refactors the UI composition logic by extracting it from `MainActivity` into a new, dedicated `RootScreen` composable. This improves the separation of concerns and simplifies `MainActivity`. Additionally, a bug has been fixed where a replied-to message would incorrectly display the author of the parent message instead of its own author. Key changes: - Moved theme setup, permission handling, Long-Poll/Online service management, and navigation graph hosting into the new `RootScreen.kt`. - `MainActivity` is now significantly simplified, delegating its UI composition to `RootScreen`. - Corrected the user and group assignment for `replyMessage` in `MessagesRepositoryImpl` to ensure the correct author is displayed. - Introduced `OnlineFriendsViewModel` to the `FriendsRoute` to separate the logic for online friends. - Replaced `List` with a custom `ImmutableList` for `photoViewerInfo` state to improve Compose stability.
