feat: 添加 AI 目录功能和相关逻辑

- 在 `MeetingUnifiedStatusServiceImpl`、`MeetingCommandServiceImpl` 和 `MeetingDomainSupport` 中添加 `resolveAiCatalogEnabled` 方法，用于检查 AI 目录是否启用
- 更新 `MeetingVO` 和 `MeetingCreateConfigVO`，添加 `aiCatalogEnabled` 字段
- 在 `MeetingController` 中添加 `aiCatalogEnabled` 参数，并更新响应构建逻辑
- 在前端页面中添加对 `aiCatalogEnabled` 的处理，包括 `MeetingDetail`、`MeetingPreview` 和 `MeetingPreviewView` 页面
- 在 `sys-params/index.tsx` 中添加 `MEETING_AI_CATALOG_ENABLED` 系统参数配置
- 更新 `AndroidPushGrpcService` 中的平台枚举，增加新的平台类型
- 优化 `AiTaskServiceImpl` 中的任务调度逻辑，支持并行和串行模式
