Unified Search Helper:
        Introduction of the ipa_search static method inside the main IPA role class that provides:
        A generic IPA CLI command execution and output parsing framework.
        Simplifies search logic across IPA entity classes like HBACService, HBACServiceGroup, HostGroup, and HBAC.
        Returns consistent, flat lists of attribute values from search results.
        Standardizes use of the --all option and multi-block output parsing.
