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

"""JOOX 歌词(对应 sdk/joox/lyric.ts,上游 joox/lyric.go 移植)。
主通道:GET https://api.joox.com/web-fcgi-bin/web_lyric?musicid=<id>&country=sg&lang=zh_cn
响应形如 ``MusicJsonCallback({"code":0,"lyric":"<base64>"})``,lyric 为 base64 UTF-8 歌词。
实测(2026-10):该旧接口仍可用(同域的 web_get_songinfo 已 404,但 web_lyric 未下线)。
兜底:openjoox2 /track 详情的 ``lrc_content``(同为 base64)。
解码:base64 → UTF-8 → HTML 实体(&amp; 等)→ ``{ lyric, tlyric: "" }``。
QRC(``qrc_content``,XML 格式)上游与 TS 均未解析,此处同样不解析,避免引入未验证逻辑。
