fix(resources): lower memory requests to fix ArgoCD controller scheduling

metrics-server activation triggered simultaneous HPA scale-ups, exhausting
node request budgets despite sufficient physical RAM. ArgoCD application-
controller (256Mi request) could not schedule on either node.

- argocd controller: 256Mi → 128Mi request (unblocks scheduling immediately)
- nowchess services: 128Mi → 96Mi request (prevents HPA cascade from filling nodes)
