refactor: 拆分 platform 模块（Auth/Users/Roles/Permissions/Menus/Notifications 从 rag 独立）

- 新建 modules/platform 三层模块（Domain/Application/Infrastructure）
- 搬入 8 个实体（User/Role/Permission/UserRole/RolePermission/RefreshToken/Menu/Notification）
- 新建 PlatformDbContext（连 platform 库）+ 8 个 EF 配置 + SeedData
- 搬入 92 个 Application CQRS 文件 + 57 个 Host Endpoints
- RagDbContext 瘦身：只留 RAG 专属表（KnowledgeBase/Document/ChatMessage/Conversation）
- Handler 注入改为 PlatformDbContext
- appsettings 新增 DatabaseNames:Platform
- BuildFlowHostModule 注册 PlatformDbContext + DependsOn PlatformApplicationModule
- Conversation 实体去掉 User 导航（跨模块不直接引用实体）
- rag SeedData 清空（平台种子归 platform）
- 暂移除测 platform 功能的 Rag.Tests（后续建 platform 测试项目）
- build 0/0
