/**
 * Generic event handler for RPC methods.
 *
 * Retrieves the RPC method name from the request path and extracts the payload:
 * - For `POST` / `PUT` / `DELETE`, the payload is read from the JSON
 *   request body as `{ payload: ... }` (compatible with the RPC client).
 * - For `GET`, expects a JSON-serialized payload in a single query field `payload`.
 *   If present, the handler parses the string using `JSON.parse(payload)`.
 *   If `payload` is missing the RPC receives `undefined`.
 *   A non-string `payload` value (e.g. repeated keys producing an array) or invalid
 *   JSON results in a `400` error response.
 *
 * It utilizes hooks provided by Nitro to allow for custom logic before,
 * after, and in case of errors during RPC calls.
 *
 * @param event The H3 event object.
 *
 * @returns The result of the RPC call or a `Response` object with an error status.
