重构表结构：合并 profiles→users，展平 API 响应，新增计数器字段

- models: 删除 Profile 模型，字段合并到 User；User 新增云朵/公开/收藏计数器；Cloud 新增 favorite_count
- schemas/serializers: 展平 UserOut/AuthOut/MeOut/AdminUserOut，移除嵌套 profile
- deps: user.profile.role→user.role，移除 selectinload profile
- auth/register: 注册时直接设置 user 字段，不再创建 Profile
- clouds: 创建/删除云朵时同步 user.cloud_count 计数器，状态变化时同步 public_cloud_count
- favorites: 点赞/取消时同步 cloud.favorite_count 计数器
- admin: 审批/隐藏/批量删时同步 public_cloud_count 计数器
- profiles/stats: 用计数器替代实时 COUNT 查询
- alembic: 新增 migration 合并 profiles 到 users，初始化 counters
