feat: 将 AuthModalProvider 迁移到 Redux

## 主要改动

### 新增
- 创建 `store/slices/authModalSlice.js` - Redux Slice 管理认证弹窗状态
- 创建 `hooks/useAuthModal.js` - 自定义 Hook，组合 Redux 状态和业务逻辑

### 修改
- 更新 `store/index.js` - 添加 authModal reducer
- 更新 `App.js` - 移除 AuthModalProvider 包裹层
- 更新 5 个组件的 import 路径：
  - AuthFormContent.js
  - AuthModalManager.js
  - WechatRegister.js
  - HomeNavbar.js
  - ProtectedRoute.js

### 删除
- 删除 `contexts/AuthModalContext.js` - 旧的 Context 实现

## 迁移效果

- ✅ 减少 Provider 嵌套层级（4层 → 3层）
- ✅ 统一状态管理架构（Redux）
- ✅ 更好的调试体验（Redux DevTools）
- ✅ 保持 API 兼容性（无破坏性修改）

## 技术细节

- 使用 `useRef` 存储 `onSuccessCallback`（函数不可序列化）
- 保持与 AuthContext 的依赖关系（AuthProvider 暂未迁移）
- 所有业务逻辑保持不变，仅改变状态管理方式
