implementing vesting delegations card - issue 284

kindly note that due to HAFBE backend not supporting querying vesting delegations, we performed the query relying on condenser_api.get_vesting_delegations

api/common/useVestingDelegations.ts

+import { useQuery } from "@tanstack/react-query";
+import fetchingService from "@/services/FetchingService";
+
+const useVestingDelegations = (delegatorAccount: string, startAccount: string | null, limit: number) => {
+  const {
+    data: vestingDelegationsData,
+    isLoading: isVestingDelegationsLoading,
+    isError: isVestingDelegationsError,
+  } = useQuery({
+    queryKey: ["vestingDelegations", delegatorAccount, startAccount, limit],
+    queryFn: () => fetchingService.getVestingDelegations(delegatorAccount, startAccount, limit),
+    refetchOnWindowFocus: false,
+  });
+
+  return { vestingDelegationsData, isVestingDelegationsLoading, isVestingDelegationsError };
+};
+
+export default useVestingDelegations;
