Adriano f665bffb7a fix: Task back button navigates to correct recipe (not version_id)
- Add recipe_id property to RecipeTask model (via version relationship)
- Add recipe_id to TaskResponse schema
- Eager-load version in _get_task_or_404 query
- Use task.recipe_id instead of task.version_id in task_execute template URLs
