[I] Metrics query responses discard Prometheus informational annotations [rocketmq-dashboard]

pilichoumao opened a new issue, #6894:
URL: https://github.com/apache/rocketmq-dashboard/issues/6894

   ### Description
   
   On `rocketmq-studio` at `a92c23144408cdf5729707050e9ecd9b75f1bad0`, Prometheus-compatible range query responses preserve `warnings` but drop the HTTP API's separate `infos` annotations. `AbstractPrometheusCompatibleMetricsSource.parseResponse` only copies warnings; `MetricDataVO`, the web API type, and MetricsExplorer cannot carry or display infos.
   
   These annotations explain potential query/data issues even when the request succeeds. For example, Prometheus can report that histogram_quantile repaired non-monotonic bucket counts. Operators currently see the values without that explanation, including when an annotated query returns no series.
   
   ### Reproduction
   
   Return a successful matrix response with `infos: ["input to histogram_quantile needed to be fixed for monotonicity"]` from a loopback query_range endpoint, and call the production `query` method. The serialized Studio response drops infos while retaining series and warnings.
   
   ECS research against the exact production parser: two annotated cases fail, two controls pass. A minimal propagation prototype preserves all four cases and passes the 21 existing PrometheusMetricsSource tests. This used an HTTP fixture, not a live Prometheus or ARMS service.
   
   ### Expected behavior
   
   Preserve infos separately from warnings, render them as informational notices (also for an empty result), and tolerate responses from compatible backends/older Studio servers that omit infos. Do not change query success, samples, or warning severity.
