fix(gluetun): prevent OOM crash and stale ip rule on container restart

- Increase memory limit 128Mi → 512Mi (DNS block list download needs ~200MB)
- Add command wrapper that cleans stale ip rules before exec'ing gluetun
  so container restarts within the same pod don't fail with "file exists"
- Fix deprecated VPN_ENDPOINT_IP/PORT → WIREGUARD_ENDPOINT_IP/PORT
