refactor: 优化账户过期检查逻辑和代码一致性

## 主要改进

### 1. 添加缺失的过期检查方法
- 在 `claudeConsoleAccountService` 中添加 `isSubscriptionExpired()` 方法
- 在 `ccrAccountService` 中添加 `isSubscriptionExpired()` 方法
- 与其他 7 个账户服务保持一致的实现方式

### 2. 统一过期检查逻辑
- 重构 `unifiedClaudeScheduler` 中的 5 处手动日期检查代码
- 统一调用服务层的 `isSubscriptionExpired()` 方法
- 消除重复代码，提升可维护性

### 3. 统一字段映射顺序
- 调整 Claude 账户更新端点的 `mapExpiryField()` 调用时机
- 与其他账户类型保持一致的处理顺序
- 提升代码可读性和一致性

## 技术细节

**修改文件**:
- `src/services/claudeConsoleAccountService.js`: 添加 `isSubscriptionExpired()`
- `src/services/ccrAccountService.js`: 添加 `isSubscriptionExpired()`
- `src/services/unifiedClaudeScheduler.js`: 5 处调用统一为服务方法
- `src/routes/admin.js`: 统一字段映射顺序

**改进效果**:
- ✅ 代码一致性提升：所有账户服务统一实现
- ✅ 可维护性提升：过期逻辑集中管理
- ✅ 减少重复代码：消除 4 处重复实现
