feat(login): kg/tx 登录态自动续期(移植 lx-music-api-server 方案)

- kg: login_by_token 续期(AES-256-CBC + RSA 裸加密,参考其 refresh/kg.py),新 token 回写 data/auth.json
- tx: 新增 sdk/auth/tx.ts —— cookie 解析、VIP 检测(vip_login_base)、
  music.login.LoginServer 续期(走既有 musicu.fcg 未签名通道,最佳努力)
- 调度:启动 10s 后首刷 + 每 24h 一次(对齐参考项目 86400s + next_run_time=now)
- /login/tx 支持可选 App 抓包凭据(openId/accessToken/refreshToken/refreshKey)
- 新增 POST /login/refresh 手动续期;/login/status 增补 tx 字段与更新时间
- 补充 /login/tx 文档行与 smoke 测试

// QQ音乐凭据 —— cookie 解析、VIP 检测与登录态续期(music.login.LoginServer)
// 与 lx-music-api-server 的 refresh/tx.py 对齐,但走本项目既有的 musicu.fcg 未签名通道
// (与 apis/tx.ts 一致);Login/VipLogin 模块若拒绝未签名请求则以 code != 0 失败,
// 此时保留原凭据并抛错,由调用方记录日志。
// 续期条件:仅浏览器 cookie(无 openId 等抓包字段)时只带 musicid/musickey 尝试,
// 失败率较高;完整凭据(/login/tx 可选传入 openId/accessToken/refreshToken/refreshKey)最可靠。
