Fix CI: Update pipelines for correct simulator builds

- Updated `.github/workflows/maven.yml`:
  - Replaced manual Android emulator script with `reactivecircus/android-emulator-runner@v2`.
  - Added explicit `xcodebuild` step for iOS to compile the generated Maven source into a `.app` bundle.
  - Configured Android tests to use API 31 and KVM permissions.
  - Set timeouts for all jobs.
- Updated `scripts/ci/run-ios-simulator.sh`:
  - Added existence check for `APP_BUNDLE`.
  - Improved runtime detection and logging.
- Deleted `scripts/ci/start-android-emulator.sh` as it is replaced by the GitHub Action.
