feat: 添加MinIO文件系统支持并优化外部连接器功能

- 添加MinIO用户文件系统配置选项(BEAVER_MINIO_ROOT_USER等)
- 更新外部连接器配置结构，包括BASE_URL和认证令牌设置
- 改进connector provider支持更多类型(official, feishu_bot等)
- 实现Mistral模型推理模式支持reasoning_effort参数
- 增强外部连接器策略配置和运行时配置管理
- 添加connector bridge事件验证和安全保护机制
- 优化任务路由逻辑，区分simple_chat和new_task场景
- 更新初始技能工具提示配置，分离authoring admin功能
