 * `InvalidRoute: Could not route to /accounts/workers/scripts/...`
 * because an empty account ID was interpolated into the API path, plus
 * placeholder values ("-", "dummy", "test", "mock") producing the same
 * class of failure. `validateAccountId` turns all of those into a
 * typed `AuthError` with an actionable message before any API call.
