Feature Request: Recipes - Consider min. stock when adding missing ingredients to the shopping list

Hi there,

when I want to add all missing ingredients from a recipe to the shopping list, Grocy is currently not considering the minimum stock of an ingredient. In the below described example, this becomes an issue (at least for me :D ):

Example use case: I defined my minimum stock of pasta to be 500g. Currently I have 500g of pasta in my stock -> No need to buy more. Now I would like to cook a recipe which needs 500g of Pasta. I still need to buy some missing ingredients to cook the recipe. For this reason I have to go to the supermarket. Before doing so, I ask Grocy to add all missing ingredients of the recipe to the shopping list.

Problem: In the above-described use case, Grocy only adds all the missing ingredients to the shopping list. Since I have 500g of Pasta in stock (=min stock) and 500g are needed for the recipe, Grocy doesn't add it to the shopping list. After going to the supermarket and cooking the recipe, I have consumed 500g of pasta. Since my minimum stock for Pasta is 500g, there is now 0g of Pasta in stock and I need to go to the supermarket again to refill my stock (not nice, since I have already been to the supermarket to buy the missing ingredients for the recipe).

Solution: To solve this problem, it would be great if Grocy would consider the minimum stock of ingredients when adding them to the shopping list. Following this logic, Grocy should also add 500g of Pasta to the shopping list in the above-described example (so that I don't run below minimum stock after cooking the recipe). This (for example) saves me on the next day, when I'm to busy to go shopping but still have my minimum stock of pasta to cook a quick meal.

What do you think about this feature?

I also want to use this opportunity to say thanks to this amazing project! I'm loving it!
