feat(crawler): 增加QQ无效专辑封面回填功能

- 在 run_etl.py 添加 backfill-qq-invalid-covers 命令行选项
- 配置文件中新增 HTTP_TRANSFER_RETRIES 和 RETRY_BACKOFF_SECONDS
- oss.py 中实现下载资源的重试逻辑，避免超时和连接断开失败
- runner.py 中引入资源必要性校验，确保音频、封面、歌词均成功转存
- 实现根据歌词和封面有效性选择更合适的QQ录音记录进行替换
- 实现 backfill_qq_invalid_covers 函数，处理无专辑占位封面的QQ歌曲
- 无候选的QQ歌曲在crawler和yinyan记录中删除，并软删除 HK 歌曲
- 资源转存失败的记录在yinyan_song_records标记，避免重复处理
- run函数中增加对QQ、酷狗、网易备选录音的支持和筛选
- 增加对应的数据库操作函数支持替换、删除以及状态标记
- 测试覆盖下载重试、资源转存失败处理及选择替代录音逻辑
- 所有下载失败均返回空URL，不阻断流程以保证稳定性
- 异常处理增强，确保未成功上传资源的歌曲不入库
- 未匹配到HK歌曲的情况增加日志警告及延迟重试机制
