/**
 * 说明：
 * - /api/actions 的鉴权在 adapter 层支持 Cookie 与 Authorization: Bearer <token>
 * - my-usage 的业务逻辑在 action 层仍会调用 getSession()（next/headers cookies/headers）
 * - 测试环境下需要 mock next/headers，否则 getSession 无法读取认证信息
 *
 * 这里用一个可变的 currentAuthToken 作为“当前请求 Cookie”，并确保：
 * - adapter 校验用的 Cookie（callActionsRoute.authToken）
 * - action 读取到的 Cookie（currentAuthToken）
 * 两者保持一致，避免出现“adapter 通过但 action 读不到 session”的假失败。
