chore: drop unused TanStack Vue Query and ts-rest client

VueQueryPlugin was mounted but no useQuery/useMutation calls existed,
and the noteRouter ts-rest contract was never imported. The callers
of api.remanso.space all use plain fetch(), so the three packages
(@tanstack/vue-query, @ts-rest/core, @ts-rest/vue-query) and the
src/modules/post directory can go.

src/modules/post/data/client.ts
