fix: create dummy .env in CI to fix asset bundling failure

The example app declares .env as a Flutter asset (needed for flutter_dotenv),
but .env is gitignored and not present in CI. This caused both Android and iOS
builds to fail with "No file or variants found for asset: .env".

Add a CI step to create a minimal dummy .env before each platform build.
