Calypso React Query Migration

Target architecture: fetchers in @automattic/api-core → query/mutation options in @automattic/api-queries → components call useQuery() / useMutation() directly.

Two source patterns migrate into it:

Redux data-layer (dispatchRequest + http actions in client/state/data-layer/wpcom/read/)
@automattic/data-stores Reader hooks (custom hooks using wpcomRequest)
