Extend "Add new agent" component

[pablotr9]

The new component where we are explaining to the user how to register agents and we are providing a "copy & paste" dynamic snippet is cool, however, it should be used in more places of the Wazuh app.

Proposals:

• [x] If the app has API entries and the API tells us there are no agents, show the component to the user, for example in Overview.
• [x] Make it accessible from more place with light buttons/icons so the user can launch the component almost everywhere.

• Overview general https://github.com/wazuh/wazuh-splunk/commit/924af6af1c26883472b07a7a3a1d005c9e495ea6: A warning message have been added so the user can access the guide from this section:
• Management -> Groups https://github.com/wazuh/wazuh-splunk/commit/a2f3f76fb7e86e039dcf809edc9e040f60559d50 : It has also been added to the Group tab, as there is no sense managing groups when there are no registered agents:
