Add an option to easily save the Wazuh server address in the "Deploy new agent" section

[s-ocando]

Describe the solution you'd like

An all-in-one deployment, in which all the Wazuh central components are installed on the same server, is very common. For example, the OVA or the installation resulting from following the Quickstart section.

In the Agents > Deploy new agent section, we find that the suggested Wazuh server address is localhost for this type of deployment.

This localhost suggestion is useless, and the user has to enter the server address every time he wants to deploy a new agent.

To modify the default value, the user has to go to Settings > Configuration and edit the Enrollment DNS value. This process is not trivial nor known by many users.

My suggestion is to add a button to easily save the Wazuh server address. See the image below.
