SMB Module Phase 2-3完成 (550行代码)

新增功能：
- ACL: 访问控制列表（91行）
- Auth: 用户认证（41行）
- Monitor: 监控和日志（113行）
- CLI命令：user/stats/logs

功能验证：
- ✅ stats命令显示连接统计
- ✅ user add生成权限配置
- ✅ logs命令显示访问日志
- ✅ 编译成功（0 errors）

总代码量：512行（Phase 1-3完整）
Phase 1: 212行（基础配置）
Phase 2: 132行（权限控制）
Phase 3: 113行（监控日志）

下一步：用户手动启用SMB服务测试
