定价统一：专业版包年 ¥99 / 永久 ¥199（与 OpsXShell 一致）；授权真实链路验证

- /pricing 与落地页：¥299 终身→¥199 永久、¥69→¥99、个人版更名专业版（3/5 台设备）；
  补 Apipost 离线版式购买叙事（一机一码/当场发证/无需注册/年 2 次免费换绑）
- 授权服务器（licence.rlwj.cn）：opsxapi 永久计划 299→199；注册 opsxdb 产品与
  trial/yearly/perpetual 计划——三产品公开 API 均为 0/99/199
- 真实链路验证：管理端签发 opsxapi 在线 LIC-（activate/verify 全通，Ed25519 签名下发）+
  离线 LICOFF-（绑本机 device_id）；新增 4 项 Rust 单测用真实 fixture 跑通
  （离线验签/换设备拒绝/篡改拒绝/在线响应签名）
