Keep deploy-app-runner.sh completely agnostic

The deployment script should remain generic with placeholder values,
while config.env.template contains RAW Labs defaults. This ensures:
- .github/ scripts are truly stable and reusable
- Project-specific values come from deployment/config.env
- No hardcoded vendor-specific values in deployment logic
