fix: 修复 AIVideoGenerator 组件中的 Store Hooks 使用错误

🔧 **Store Hooks 修复**：

1. **问题识别**：
   - useAIVideoJobs, useAIVideoProcessing, useAIVideoSettings 使用方式错误
   - 缺少 useAIVideoStore 主 store 的导入
   - 函数名不匹配：generateBatchVideos vs batchGenerateVideos

2. **修复内容**：
   - 添加 useAIVideoStore 导入
   - 正确使用 selector hooks：
     * useAIVideoJobs() → 返回 jobs 数组
     * useAIVideoProcessing() → 返回 isProcessing 布尔值
     * useAIVideoSettings() → 返回设置对象
   - 通过主 store 获取 actions：
     * generateSingleVideo
     * batchGenerateVideos
     * clearCompletedJobs

3. **Store 架构理解**：
   - **Selector Hooks**: 用于获取特定状态片段
   - **Main Store**: 用于获取 actions 和复杂操作
   - **类型安全**: 所有 hooks 都有正确的 TypeScript 类型

4. **函数调用修复**：
   - generateBatchVideos → batchGenerateVideos
   - 保持与 store 定义的一致性

✅ **修复效果**：
- 编译错误消除 ✓
- Store 状态正确访问 ✓
- Actions 函数正常调用 ✓
- TypeScript 类型检查通过 ✓

现在组件可以正确使用 Zustand store 进行状态管理！
