fix(frontend): 修复 TypeScript 类型错误，与后端 API 响应结构对齐

- 修复 UserDTO 类型定义，字段改为非 nullable 类型
- 修复 PostMapper 使用正确的 snake_case 字段名
- 修复 UserMapper 移除不存在的 is_blocked 和 updated_at 字段
- 修复 MessageMapper 使用 segments 替代已移除的字段
- 修复 MessageSyncService 正确处理 API 响应类型
- 修复 LocalDataSource SQLite 参数类型问题
- 修复导航相关类型错误
- 修复 PostDetailScreen 和 EditProfileScreen 的 null/undefined 类型不匹配
