Feature request to improve the filtering options in the Hosts view.

Current behavior:

In Data Collection → Hosts, the filter allows selecting only a single Host Group at a time.  
This limits the ability to quickly view hosts that belong to multiple specific groups simultaneously.

Request:

Enable the ability to filter hosts by multiple Host Groups at once, similar to how the filtering works when selecting a Proxy (where multiple proxies can be chosen).

Possible implementation:

• Convert the Host Group filter to a multi-select control.
• Allow AND / OR logic (optional enhancement).
• Maintain compatibility with existing group-based permissions.

Benefits:

Gives administrators more flexible and efficient filtering.

• Reduces time spent navigating between individual groups.
• Helps in environments with complex group structures and overlapping categories.
