Creates an intake for the specified APIUser without using an image-based prediction. This is an alternative to the recognition endpoints.

Each food item must provide either:

1. A valid dish id obtained from /dataset/dishes; and/or
2. A non-empty ingredients list containing valid ingredientId values obtained from /dataset/ingredients.

Optionally, quantity, levels, and ingredients can be specified for each food item. If both a dish id and ingredients are provided, the supplied ingredients replace the default recipe for that dish. The parameters are applied in the following order:

1. Ingredients: Define or replace the food item's recipe.
2. Levels: Scale the level of salt, sugar, and oil. Ingredient weights may be altered when this parameter is included.
3. Quantity: Scale ingredient quantities proportionally so that their total matches the provided quantity.
