Fix androidTest packaging and stabilize instrumented navigation checks

Browse Source 
Move test-only dependencies out of commonMain to stop androidx.test classes leaking into app runtime, which fixes missing ActivityInvoker in the test APK. Also update instrumented tests to use Compose resource APIs correctly, make navigation assertions resilient to emulator back-stack variance, and use version-catalog lifecycle testing deps where required.
