Use test dispatcher & real DatabaseService in tests

Add mockk android test dependency and refactor RealmUserTest to use a real DatabaseService constructed with a test DispatcherProvider (all dispatchers set to Dispatchers.Unconfined). Removed the previous manual anonymous DatabaseService implementation and adjusted imports (added CoroutineDispatcher). This simplifies coroutine testing and ensures the database service uses a consistent test dispatcher and application context.
