Issue:
Bug: bug(EVENT_VIEWER): connector events is missing a status code field



The status code is being always registered as `0` in clickhouse.

It seems that we aren't setting the status code at all from the application...


we should be able to extract the status code via a simple snippet
```rs
let status_code = response
    .as_ref()
    .map(|i| i.map_or_else(|value| value.status_code, |value| value.status_code)).unwrap_or_default();
```
