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-status — fires on kiosk heartbeat telemetry.
|
|
*
|
|
* Topic filter: `kiosk.status`. Server's nodered-bridge POSTs to
|
|
* `${noderedUrl}/in/kiosk.status` directly. This node self-registers its
|
|
* own POST handler — no upstream `http in` node required.
|
|
*
|
|
* Optional config:
|
|
* - kiosk_id: only fire for that kiosk id
|
|
*
|
|
* Output msg.payload:
|
|
* { kiosk_id, kiosk_name, cpu_temp_c, fan_rpm, fan_pwm }
