[Bug] FE metric http_copy_into_query_err_total is registered under the upload error name

Il bug si trova in fe/fe-core/src/main/java/org/apache/doris/metric/MetricRepo.java, righe 834-842. Il nome della metrica per HTTP_COUNTER_COPY_INFO_QUERY_ERR dovrebbe essere 'http_copy_into_query_err_total'. Modificare la stringa, quindi avviare il FE ed eseguire il comando curl dell'issue per verificare che la nuova metrica appaia e che il contatore degli errori di upload sia separato.

What's Wrong?

In MetricRepo, the counter HTTP_COUNTER_COPY_INFO_QUERY_ERR is registered with the name of the upload error counter:

https://github.com/apache/doris/blob/573c93c63b88fb68ac1d318dcd3e1672dd2361e6/fe/fe-core/src/main/java/org/apache/doris/metric/MetricRepo.java#L834-L842

HTTP_COUNTER_COPY_INFO_UPLOAD_ERR = new LongCounterMetric("http_copy_into_upload_err_total",
        MetricUnit.REQUESTS, "http copy into upload err request");
...
HTTP_COUNTER_COPY_INFO_QUERY_ERR = new LongCounterMetric("http_copy_into_upload_err_total",
        MetricUnit.REQUESTS, "http copy into err query request");

DorisMetricRegistry keys metrics by name and labels, and MetricList.addMetrics replaces an existing entry with the same key:

https://github.com/apache/doris/blob/573c93c63b88fb68ac1d318dcd3e1672dd2361e6/fe/fe-core/src/main/java/org/apache/doris/metric/DorisMetricRegistry.java#L42-L51

The query error counter is registered second, so it replaces the upload error counter. As a result:

• doris_fe_http_copy_into_upload_err_total reports the query error count.
• The upload error count is never exported. CopyIntoAction still increments HTTP_COUNTER_COPY_INFO_UPLOAD_ERR, but the registry no longer holds it.
• doris_fe_http_copy_into_query_err_total does not exist.

CopyIntoAction increments HTTP_COUNTER_COPY_INFO_QUERY_ERR only on the query path, so the counter is correct but its name is wrong.

What You Expected?

The query error counter is exported as doris_fe_http_copy_into_query_err_total, which matches the naming of the other three copy-into counters (http_copy_into_upload_request_total, http_copy_into_upload_err_total, http_copy_into_query_request_total).

How to Reproduce?

1. Start an FE.
2. Run curl http://<fe_host>:<http_port>/metrics | grep http_copy_into.
3. doris_fe_http_copy_into_upload_err_total appears once and counts query errors. doris_fe_http_copy_into_query_err_total does not appear.

Anything Else?
