Fix Android CI Java version and Maven plugin classpath

- **Android CI:**
  - Updated `.github/workflows/scripts-android.yml` to explicitly set `JAVA_HOME` to Java 17 for the `reactivecircus/android-emulator-runner` step. This resolves `UnsupportedClassVersionError` in `sdkmanager` (which requires Java 17+), ensuring the Android SDK and emulator are correctly initialized within the CI container (where the default `JAVA_HOME` is Java 8).

- **Maven Plugin:**
  - Modified `maven/codenameone-maven-plugin/pom.xml` to move `xalan` and `serializer` dependencies to the top of the dependency list. This prioritizes them on the classpath over `codenameone-designer` (a fat jar), resolving a `NoClassDefFoundError: org/apache/xml/serializer/OutputPropertiesFactory` that occurred during CSS compilation in archetype integration tests.
