Details 
The Dockerfile's NODE_OPTIONS=--max-old-space-size=64 was added to keep
idle Node memory low, but in practice it OOMs wgc router compose as soon
as the supergraph has more than a handful of subgraphs:

  FATAL ERROR: Ineffective mark-compacts near heap limit
  Allocation failed - JavaScript heap out of memory

Bake the higher cap into the image and raise the container memory limit
(k8s/deploy.yaml) so the cgroup doesn't kill the pod at the new ceiling.
Memory request stays modest so the pod still schedules tightly when idle.

The live k8s.unbound.se cluster was already patched in place (kubectl
set env + set resources). This commit makes the manifest match.
