fix: disable enableServiceLinks on paperless pod to stop gunicorn crash-loop

Service "paperless" made k8s inject PAPERLESS_PORT=tcp://<ip>:8000 as a legacy Docker-links env var, which paperless-ngx's own entrypoint also reads for gunicorn's bind port - collided, gunicorn crash-looped ("not a valid port number"), and the pod was 1/1 Running with nothing actually listening (nginx saw 502).
