Description

This PR fixes the KeyError: 'msg_sent' bug in the tool to be able to plot the remoted statistics data. This bug caused the images not to be generated in the cluster test pipeline.

After the fix, you can see how the images are generated correctly.

    ├── wazuh-remoted_stats_recv_bytes.svg
    └── wazuh-remoted_stats_tcp_sessions.svg

Regarding the monitoring of the stats, no changes were necessary, since all the lines of the wazuh-remoted.state file are dynamically parsed.
