feat(huawei-review): 华为审核开关(admin 可切 + 客户端下发 + 审计) (#147)

华为应用市场审核要求新手引导的「快速设置」权限步必须可被用户关闭,平时又要
保住权限开启率,故做成后台可切的两态开关,送审期间切开、过审后收回。

- app_config 新增 huawei_review 行(default / review),空库与脏值一律回退
  default = 上线至今的现状,宁可不给退出按钮也不误放开
- admin: GET/PATCH /admin/api/huawei-review,权限 operator/tech,切换写审计
- 客户端: GET /api/v1/platform/huawei-review 不鉴权(引导页在登录前就展示),
  下发 onboarding_closable;机型 gate 由客户端做,故此处不判 ROM
