List client contact methods
Lists the Client's methods - at most one email and one conventional phone. No filters, sorts or includes: a method only ever exists under its parent, never resolved on its own.
Each entry carries `channel`, `value`, `created_at`, `updated_at`; there is no `self` link (a method has no standalone show route).
A read-only token is enough. A Contact id on this URL answers 404.
