feat: implement Iteration 5 — home screen dashboard

Backend:
- internal/home: GET /home/summary endpoint
  - Today's meal plan from menu_plans/menu_items
  - Logged calories sum from meal_diary
  - Daily goal from user profile (default 2000)
  - Expiring products within 3 days
  - Last 3 saved recommendations (no AI call on home load)
- Wire homeHandler in server.go and main.go

Flutter:
- shared/models/home_summary.dart: HomeSummary, TodaySummary,
  TodayMealPlan, ExpiringSoon, HomeRecipe
- features/home/home_service.dart + home_provider.dart
- features/home/home_screen.dart: greeting, calorie progress bar,
  today's meals card, expiring banner, quick actions row,
  recommendations horizontal list
