ci: refine Google Play JSON handling and remove debug steps

This commit updates the Android CI workflow to:

-   Move the Google Play JSON file from the `secrets/app/` directory to `app/`.
-   Ensure the `app/` directory exists before moving the JSON file.
-   Remove redundant `Debug Secrets` steps from the `deploy-beta` and `deploy-firebase-internal` jobs.
