/**
 * Retrieves the first active campaign.

 * simplifying the process of fetching data. It internally calls `useRpc`
 * with the provided parameters and options.
 *
 * @param params An object containing parameters and options for the `getCampaign` RPC call.
 * @param params.options The options for the underlying `useRpc` call, controlling data handling and loading state.
 * @param key A unique key for this RPC call. Used internally by `useRpc` for caching and state management.
 *
 * @returns The result of the `useRpc` call, which includes the fetched campaign data,
 *          loading state, and any error information.
