Subject: [PATCH] Fix: Android compile errors in AuthScreen and MainScreen
 preview

- AuthScreen.kt: FocusManager is imported from androidx.compose.ui.focus,
  not androidx.compose.ui.platform (only LocalFocusManager lives there).
  The fully-qualified platform.FocusManager parameter types therefore
  failed to resolve, cascading into the clearFocus() errors.
- MainScreen.kt: MitbringslTheme gained a required sessionManager
  parameter in 729865b; the leftover template preview now passes
  SessionManager(LocalContext.current).

Verified: ./gradlew compileDebugKotlin, assembleDebug and test all green.
Note: local builds must use JDK 21 (JAVA_HOME=/usr/lib/jvm/java-21-openjdk);
the system default JDK 26 breaks AGP's JdkImageTransform (jlink) on
android-36's core-for-system-modules.jar.
