feat: API Key管理+用量追踪完整功能链路v2（真实可用） 

持久化存储:
- APIKey模型 + APIKeyRepository（SQLAlchemy）
- UsageRecord模型 + UsageRepository（SQLAlchemy）

API Key验证:
- KeyVerifier服务（真正调用引擎API验证）
- 支持9个引擎的真实性验证

加密存储:
- KeyEncryption服务（Fernet AES加密）
- 环境变量API_KEY_ENCRYPTION_KEY

用量追踪:
- UsageRecorder自动记录查询用量
- 按引擎/按日聚合（修复by_day空dict）
- UserQuotaService支持套餐配额（free:10/basic:50/pro:200/enterprise:1000）

集成修复:
- AI引擎适配器使用APIKeyManager获取Key（用户Key>系统Key>环境变量）
- SmartRouter与APIKeyManager集成（过滤无Key引擎）
- BatchQueryService自动记录用量并传递用户上下文
- 所有适配器支持引擎特定代理环境变量

前端:
- usage页面替换MOCK为真实API调用
- 显示加载/错误/空状态

测试: 630 passed
