RED.httpNode.post registers a raw express route with no body parser, so req.body was undefined and trigger payloads showed all fields null. Add a zero-dep readJsonBody helper that streams + parses req body.

/**

|
* bf-trigger-layout-changed — fires when a display switches to a new layout.
|
|
*
|
|
* Topic filter: `layout.changed`. Server's nodered-bridge POSTs to
|
|
* `${noderedUrl}/in/layout.changed` directly. This node self-registers its
|
|
* own POST handler — no upstream `http in` node required.
|
|
*
|
|
* Optional config:
|
|
* - display_id: only fire for that display id
|
|
*
|
|
* Output msg.payload: { display_id, kiosk_id, layout_id, layout_name }
