fix: Disable IAM enforcement in LocalStack service container

- Set ENFORCE_IAM=0 to accept any AWS credentials
- Add SKIP_SSL_CERT_DOWNLOAD=1 to skip certificate validation
- Add CORS disable flags for simpler testing
- Resolves 'security token included in the request is invalid' error
- LocalStack now accepts the test/test credentials from tests
