Fix CI: Resolve JDK versions for Android and runtime detection for iOS

- Updated `.github/workflows/maven.yml`:
  - Android job now installs JDK 17, then JDK 11.
  - JDK 17 is saved to `JAVA17_HOME` and explicitly used for Android SDK tools (`sdkmanager`, `avdmanager`) and the native build step to satisfy requirements.
  - JDK 11 remains the default for `mvn install` and other build tasks.
- Updated `scripts/ci/run-ios-simulator.sh`:
  - Added auto-detection logic to find the latest available iOS runtime if the specific requested version is missing, resolving failures on `macos-15` runners.
- Updated `scripts/ci/build-thirdparty-app.sh`:
  - Removed `hellocodenameone` fallback logic; strictly targets `APP_DIR`.
  - Removed implicit `LATEST` version overriding to fix Maven validation errors.
