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.

* RED.httpNode.post(path, handler) registers a raw Express route with no

* body parser, so req.body is undefined. Trigger nodes call readJsonBody(req)
|
|
* to get a parsed object (or {} on error / non-JSON).

|

|
|
* Zero dependencies — avoids relying on Node-RED's bundled body-parser being
|
|
* resolvable from our nodesDir.
