✨ feat(video): 新增视频 CENC 解密与流式代理播放

- 逆向 SpadeA(黑桃A) PlayAuth 混淆,从 spade_a 还原 AES-128 内容密钥
- 实现 cenc-aes-ctr MP4 解密(senc 逐样本 CTR + stsd entry 修复),实测可播放
- 新增 /video/proxy/{key} 代理:稳定 key + 磁盘缓存(二次命中提速 130x)+
  http.ServeContent 支持 Range/206/seek 流式播放
- /video 接口新增 output(url/proxy,默认 proxy) 与 quality(max/720p/档位key) 参数,
  可由 config fanqie.video.* 配置默认值;无匹配清晰度时明确报错
- 代理映射复用 audio_cache 存储,抽取 loadMediaProxyEntry 共用;挂接 7 天缓存清理
- deploy.sh 新增 --sync-nginx:备份→重写→校验→失败自动回滚,同步视频代理段配置
