ApiError.fromDio handles both server envelope shapes: {"error":"code"}
(admin endpoints) and {"error":{"code","message"}} (most others). Same
dual-shape problem the web apiFetch already solves. Token comes from a
resolver function so the auth provider can swap implementations
without touching the client.
ErrorCopy is a lazy singleton over assets/error-copy.json with the
same fallback chain web uses (specific code -> unknown -> hard-coded).
