fix: TS errors + Docker Compose running locally

- Removed unused imports (PublicRoute, GripVertical, addFromRecipe, X, ShoppingGroup)
- Fixed HouseholdCard unused var
- Fixed ShoppingPage household query (missing queryFn)
- Killed tmux sessions, app runs fully on Docker now
- 3 containers: db (postgres:17), backend (node:22), frontend (nginx)
