ci: Improve E2E test reliability and observability

Fixes a timing issue in the example app's E2E test by delaying the `stop()` API call. This ensures the SDK has sufficient time to receive `onInstallConversionData` before being stopped, preventing premature termination of the request.

Enhances CI workflows to:
*   Update the iOS build cache key to include `example/.env`, ensuring a fresh build when environment variables change and preventing stale test configurations.
*   Log `.env` keys (with values redacted) during workflow runs for better debugging without exposing secrets.
