fix: 修复4个后台列表页点击排序失效，清理2个页面的死SortMixin代码

问题：SortInterceptor 从URL query读取sort，但前端统一在body发送，
导致 AdminRecipe、AdminCoupon、AdminAssessmentOrder、AdminTask、
AdminSubscription 五个接口排序不生效。

后端修复（5个文件）：
- AdminRecipeController / AdminCouponController / AdminSubscriptionController：
  从@RequestBody读sortSpecs，调用SortUtil.applySort(wrapper, sortSpecs, null)
- AdminRecipeController / RecipeService：新增listByMealType(mealType, sortSpecs)重载，
  原无参方法保留供MealRecommendService调用
- AdminController.getTasks() / getAssessmentOrderList()：同模式替换SortUtil.applySort(wrapper)
- CouponService：新增listAll(sortSpecs)重载，使用QueryWrapper+SortUtil

前端修复（2个文件）：
- AssessmentOrders.vue / SubscriptionManagement.vue：
  移除死SortMixin（无排序触发逻辑），清理sort-header/sort-tag CSS
