Enable Spotless verification for Android Port and consolidate reporting

- Added `spotless-maven-plugin` to `maven/android/pom.xml` configured for `Ports/Android/src`.
- Updated `scripts/build-android-port.sh` to run `spotless:check` and capture results to a report file.
- Modified `scripts/lib/cn1ss.sh` and `scripts/run-android-instrumentation-tests.sh` to append the Spotless report to the main Android status comment.
- Updated `scripts/run-android-instrumentation-tests.sh` to fail the build if Spotless checks failed, after reporting is complete.
- Updated `.github/workflows/scripts-android.yml` and reporting scripts to suppress noisy "missing report" warnings and correctly collect test artifacts.
