feat: 架构修复 - P0/P1 问题全面修复

P0 修复:
- runtimeStore: 添加缺失的 lastDayHistory 字段
- Gateway/RuntimeService: 状态同步改为内存优先，消除 glob 竞态
- App.jsx: 从 3075 行重构到 ~500 行，提取 8 个独立文件

P1 修复:
- CORS: 4 个服务改为从环境变量读取允许 origins
- MarketStore: 改为模块级单例模式
- Domain 层: 删除 trading thin wrapper，保留 news 真实逻辑
- 测试: 补齐 77 个 gateway/runtime 测试

新增文件:
- backend/tests/test_gateway.py (43 tests)
- frontend/src/hooks/useWebSocketHandler.js
- frontend/src/hooks/useStockRequestCallbacks.js
- frontend/src/hooks/useAgentCallbacks.js
- frontend/src/hooks/useRuntimeCallbacks.js
- frontend/src/hooks/useWatchlistCallbacks.js
- frontend/src/components/TickerBar.jsx
- frontend/src/components/HeaderRight.jsx
- frontend/src/components/ChartTabs.jsx
