feat: P1阶段完成 - 订单模块迁移与重构

## P1.3: 订单模块（orders）✅

### 完整迁移
- 迁移 API: orders.ts
- 迁移 Views: 5个页面（桌面3 + 移动2）
- 迁移 Composables: useOrderSnapshot.ts
- 更新所有导入路径到 shared/

### 核心重构：拆分 useOrderDetail.ts
原始文件405行，混合了订单、支付、结算、争议等多个领域

**拆分为3个独立 composables：**

1. **usePaymentPolling.ts** - 支付轮询
   - 职责：轮询查询支付状态直到完成
   - 功能：开始/停止轮询、检查支付状态、自动重载
   - 代码：~65行

2. **useSettlement.ts** - 结算流程
   - 职责：处理订单结算完整流程
   - 功能：提交/接受/反驳/确认结算、表单管理
   - 代码：~170行

3. **useOrderDetail.ts** - 核心订单（重构后）
   - 职责：订单核心流程，组合使用上述composables
   - 功能：加载、取消、支付、交接、收货、争议
   - 代码：~215行

**重构优势：**
- 职责清晰，单一职责原则
- 可复用，支付和结算逻辑可独立使用
- 易测试，每个composable独立可测
- 易维护，从405行拆分为3个文件

### 技术改进
- 建立清晰的模块边界和导出规范
- 避免循环依赖
- 提高代码可测试性和可维护性

## 里程碑

🎉 **P1 阶段完成！**

- ✅ P0: 基础设施（shared/）- 22个文件
- ✅ P1.1: 钱包模块 - 5个文件
- ✅ P1.2: 聊天模块 - 8个文件
- ✅ P1.3: 订单模块 - 11个文件

**总计：** 3个核心业务模块，46个文件完成迁移
