Today, ServerActive must contain a static list of proxies, even when Proxy Groups are used. This requires manual updates on all agents whenever the group membership changes.

Requested enhancement:
Allow configuration like:

ServerActive=ProxyGroup-Prod

 with dynamic resolution of the group members on the Zabbix side.

This would reduce operational complexity, improve maintainability, and align agent configuration with the Proxy Group concept already available on the server side.
