refactor(subscription): Phase 2 - 迁移到 Redux 状态管理

重构目标: 使用 Redux 管理订阅数据,替代本地状态

Phase 2 完成:
✅ 创建 subscriptionSlice.js (143行)
  - Redux Toolkit createSlice + createAsyncThunk
  - 管理订阅信息、loading、error、Modal 状态
  - fetchSubscriptionInfo 异步 thunk
  - resetToFree reducer (登出时调用)

✅ 注册到 Redux Store
  - 添加 subscriptionReducer 到 store

✅ 重构 useSubscription Hook (182行)
  - 从本地状态迁移到 Redux (useSelector + useDispatch)
  - 保留所有权限检查逻辑
  - 新增: isSubscriptionModalOpen, open/closeSubscriptionModal
  - 自动加载订阅数据 (登录时)

✅ 重构 HomeNavbar 使用 Redux
  - 替换 useSubscriptionData → useSubscription
  - 删除 ./hooks/useSubscriptionData.js

架构优势:
✅ 全局状态共享 - 多组件可访问订阅数据
✅ Redux DevTools 可调试
✅ 异步逻辑统一管理 (createAsyncThunk)
✅ 与现有架构一致 (authModalSlice 等)

性能优化:
✅ Redux 状态优化,减少不必要渲染
✅ useSelector 精确订阅,只在相关数据变化时更新

累计优化:
- 原始: 1623行
- Phase 1后: 1573行 (↓ 50行)
- Phase 2后: 1533行 (↓ 90行, -5.5%)
- 新增 Redux 逻辑: subscriptionSlice (143行) + Hook (182行)

下一步: Phase 3+ 继续拆分组件
