Description

with upcoming need to be "16kb alignment clean" the CI matrix for emulator tests should be updated to run against a 16kb emulator as well as a regular emulator. Suggest using this API/image-name tuple:

android-35;google_apis_ps16k

The page size should be verified in CI prior to execution, via the tests on linked google doc

Additionally, the .apk should be extracted and have .so file verification of page-alignment checked, and finally the zipalign should be checked - otherwise we won't know if we have actually done the work or not, and we won't track any random regressions

Research direction
Start by examining the repository's CI workflow files, likely in .github/workflows. The issue references PR #402 in Anki Android Backend, which contains context on 16kb page alignment. The task involves adding an emulator test using the image 'android 35;google apis ps16k' and implementing checks for .so alignment and zipalign verification. Review the linked Google doc for the exact verification commands.
