## Task OPT-16 Completed: Tab页面返回按钮修复

### Summary
已成功修复 book-generator/index.vue 作为 Tab 页时返回按钮显示问题：

1. **检测页面是否为 Tab 页**: 通过 `isTabPage` ref 标识
2. **Tab 页隐藏返回按钮**: 使用 `v-if="showBackButton"` 条件渲染，`showBackButton` 在 Tab 页返回 `false`
3. **非 Tab 页显示返回按钮**: 根据页面栈判断是否显示

### Modified Files

### Task Folder

### Status
- [x] Add isTabPage ref
