Enable Spotless verification for Android Port and improve Android quality 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` using JDK 17.
- Updated `scripts/run-android-instrumentation-tests.sh` and `scripts/generate-android-coverage-report.sh` to correctly place test results and coverage XMLs for quality reporting.
- Updated `.github/scripts/generate-quality-report.py` to support suppressing missing report sections via `QUALITY_REPORT_SUPPRESS_MISSING` env var.
- Updated `.github/workflows/scripts-android.yml` to set `QUALITY_REPORT_SUPPRESS_MISSING=1` and enable quality reporting.
