feat: Seedance 视频/音频改用 R2 预签名上传，移除插件内凭证

- 新增 utils/r2_uploader.py：通过 o1key 后端预签名接口上传视频/音频，零 R2 凭证
- seedance_video.py：视频、音频均改为 await upload_video/upload_audio，移除 base64 inline 编码
- 删除 doubao-seedance-2-0-fast 模型选项
- .config 加入 .gitignore，停止 git 追踪，防止 API Key 泄露
- base_client.py：新增系统代理自动检测（Windows 注册表 / macOS networksetup）
