In Docker Swarm with the -dns image variant, RADIUS_HOST may be a hostname that is not immediately resolvable if the target service is still starting up. Add wait_for_radius_hosts() that retries DNS resolution before writing config and starting the proxy. Configurable via RADIUS_HOST_WAIT_RETRIES (default 30) and RADIUS_HOST_WAIT_INTERVAL (default 2s), giving 60s total wait time. Closes #54
