Function get_configurations 

pub async fn get_configurations(
    infra: &InfraContext<'_>,
    token: &str,
    params: &GetConfigurationParams,
) -> Result<Vec<CfsConfigurationResponse>, Error>

List CFS configurations the caller may see.

When params.group_name is set, access to that group is validated first; otherwise the search is scoped to every group the token already grants access to. Name / pattern / date filters and the per-call limit are applied by the backend.
