feat(activity): 新增 BaseActivity 沉浸式基类和 HomeActivity 首页，统一 Activity 继承关系

- 新增 BaseActivity：继承 ComponentActivity，隐藏状态栏和导航栏，底部上滑可临时唤出导航栏
- 新增 HomeActivity（XML 版本）及对应布局 activity_home.xml，作为应用启动入口
- GoodsListActivity、FoodCollectionActivity、LocalImagePreviewActivity、PurchaseOrderActivity 统一改为继承 BaseActivity
- 更新 AndroidManifest.xml：HomeActivity 注册为启动入口
