feat: adapt recipe surfaces for batch-cook sessions

- Recipes page action buttons reordered/restyled to push AI generation
  and batch cooking ahead of manual recipe creation.
- Recipe detail page hides meal/drink pairing (doesn't make sense for
  a multi-dish batch session).
- Print pages force light mode regardless of app theme (dark bg +
  hardcoded dark text was unreadable) and render sectioned steps +
  dishes/storage for batch-cook recipes.
- Markdown export mirrors the same sectioned structure.
- Cooking mode tags each step with which dish(es) it belongs to.
- Meal planner: mealPlanEntries.batchDishId lets a slot point at one
  specific dish within a batch session; picking a batch-cook recipe
  now prompts for which dish, and the grid shows the dish name.
