fix openclaw config mount and OOM: use init container, increase memory to 2Gi

- Replace subPath ConfigMap mount with init container that copies openclaw.json
  to writable NFS home (OpenClaw writes back to the file at runtime)
- Remove invalid memory-api plugin references causing "Config invalid"
- Increase memory to 2Gi (req+limit) with NODE_OPTIONS=--max-old-space-size=1536
- Fix tg wrapper to inject -auto-approve when apply --non-interactive is used
