- MealPlanGrid: edit-mode toggle (visible when >1 meal type) reveals
per-row ↑/↓ reorder and ✕ remove controls; label column expands to
auto width via CSS class swap
- mealPlan store: removeMealType() and reorderMealTypes() — both send
the full updated array to the existing PATCH /meal-plans/{id} endpoint
- MealPlanView: wires remove-meal-type and reorder-meal-types emits;
shares mealTypeAdding loading flag to disable controls during save
- Guard: remove disabled when only one type remains (always keep ≥1)
