fix: Add AWS credentials environment variables for LocalStack tests

- Set AWS_ACCESS_KEY_ID=test for LocalStack authentication
- Set AWS_SECRET_ACCESS_KEY=test for LocalStack authentication
- Set AWS_DEFAULT_REGION=us-east-1 for AWS SDK configuration
- These dummy credentials are required by LocalStack and AWS SDK clients
