4493-4550: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Langflow playground entry has no NetworkPolicy field despite doc coverage.

langflow.mdx (same PR) documents networkPolicy.enabled and networkPolicy.extraEgress in detail, and the PR objectives claim NetworkPolicy controls are exposed for Langflow in the playground registry. This langflow config block is unchanged and still only has General and Ingress sections — no NetworkPolicy field group to let users preview/toggle this documented behavior.
