Same pattern as FreePBXTokenCache: add X-Requested-With + Accept: application/json to suppress FreePBX's HTML redirect responses, and switch all three call sites (queryOnce, restGet, restPost) from ResponseEntity<JsonNode> to ResponseEntity<String> with manual objectMapper.readTree() so non-JSON bodies produce a clear diagnostic error instead of an opaque HttpMessageConverter exception.
