Feat/pipeline enable all extensions (#1807)

* feat: 添加流水线扩展集成"启用所有"选项

为流水线的扩展集成配置添加独立的"启用所有插件"和"启用所有MCP服务器"选项。

主要变更：
- 数据模型：在 extensions_preferences 中添加 enable_all_plugins 和 enable_all_mcp_servers 字段
- 后端逻辑：修改 RuntimePipeline 以支持独立的启用所有选项，当启用时设置为 None 表示使用所有可用资源
- API 接口：更新 GET/PUT /api/v1/pipelines/{uuid}/extensions 以支持新字段
- 前端 UI：为插件和 MCP 服务器分别添加独立的开关控件
- 国际化：添加对应的中文翻译文本
- 默认行为：新创建的流水线默认启用所有插件和 MCP 服务器
