Usage:
  format-k8s-resources.sh

Reads dedicatedK8sResources JSON from stdin and formats it for display.

Expected schema (DevOps success envelope + business fields):
  {
    "errcode": 0,
    "content_type": "TEXT"|"YAML"|...,
    "content": "...",
    "truncated": false,
    "hints": "",
    "item_count": 0
  }

Behavior:
  - Prints meta: content_type, item_count, truncated, hints (if non-empty).
  - Prints content as-is in a markdown code fence (no YAML/TEXT parsing).
  - Fails if top-level "content" is missing.

Example:
  devops_http.sh --env dev --method POST \
    --path /cluster/dedicatedK8sResources \
    --query "cluster_id=123" --body '{...}' \
    --header "X-Request-ID: k8s-resource" \
  | format-k8s-resources.sh
