feat(python): 完成 Python 全量迁移——剩余平台、登录通道与公共层修复
- 新增 5sing/apple/xm/me/qt/lr 平台包与取流实现（含 xm-sign、MissEvan 签名、蜻蜓 HMAC、Apple developer token） - 新增 wy/kg/tx/lr 登录：扫码、手机号、账密（kg 20028 风控指纹）、cookie 绑定、kg/tx 续期 - request 层：保留多值 Set-Cookie；JSON body 紧凑化（修复 kg 网关验签）；直连不经系统代理（对齐 Node） - 登录路由统一 Body(embed=True)，修复扫码轮询 422；lifespan 接入登录续期调度 - ruff/format/pyright 全绿；14 平台真实联网与 HTTP 路由验证通过

"""Apple Music 公共工具（对应 sdk/apple/util.ts，上游 music-lib/apple/apple.go 的移植基础层）。
|
||||
|
||||
* ``New(cookie)`` → auth_store 的 apple 记录：cookie 支持
|
||||
``"media-user-token=xxx;storefront=cn;token=xxx"`` 形态。
|
||||
* ``fetch_apple_token``：从 music.apple.com 首页 → index-legacy JS 抓 developer token（amp-api 的 Bearer）。
|
||||
当前（2026-10）Apple 下发的 JWT 以 eyJ0eXAi 开头而非上游正则写的 eyJh，
|
||||
故这里泛化为任意 JWT（eyJ…）并优先选择 issuer=AMPWebPlay 的 token；带回退与失效重取。
|
||||
* amp 请求（httpFetch 不自动跟 302，首页跳转用 fetch_follow 手动跟）。
|
||||
* 模型转换与 ID 提取（字段映射同上游，apple_test.go 的断言逐条保留）。
