Blocklists, Clients, Domains and Upstreams each carried a ToastLike shim
that duck-typed a react-hot-toast style API. The console uses its own
Toast context, so notify() was calling toast('some message') with a string
where ToastOptions is expected: every mutation toast rendered an empty
title. They now take the toast function from useToast() and send a real
{ title, tone } payload, mapping 'fail' onto the danger tone.
