           Summary: security/wazuh-manager: agent-manager connection
                    doesn't work over TCP

With wazuh-manager 4.12.0 and wazuh-agent 4.12.0 installed on the same network,
the agent is unable to obtain a working connection to the manager over TCP,
remaining always in the HC_STARTUP state. 

Changing the client-server connection type to <protocol>udp</protocol>
magically solves the problem.

This is happening on FreeBSD 14.3, but exactly the same issue had been
previously documented on FreeBSD 13.1 with Wazuh 4.3.7:

I've spent significant amount of time debugging the TCP issues on both
machines, excluding possibility of any network or firewall problems, so it
seems like there's some nuanced OS-specific bug in Wazuh that prevents TCP
connections from working on FreeBSD.
