fix(voice-clone): source_audio_url 不做预签名转换，原样返回用户输入

source_audio_url 是用户传入的原始参考音频 URL（可能是外部地址），
不是系统内部 OSS storage key，不应该经过 storage.get_download_url
做预签名转换。之前的代码会把外部 URL 错误地当作 OSS key 处理，
导致返回无效的签名 URL。

- 删除 _to_response 中的 sign_url 调用和参数
- 清理 4 个端点中不再使用的 get_audio_url_signer 依赖注入
- 33 个 voice_clone 集成测试全绿
