Scale recipe and save

First Check

• I used the GitHub search to find a similar requests and didn't find it.
• Checked the tasks tagged issues and verified my feature is not covered

Please provide a concise description of the problem that would be addressed by this feature.

Many of the recipes I have are for 2 servings but I need them for 4. I can either import as-is and then scale every time I want to to make the recipe or edit the recipe and manually scale then save.

Please provide a concise description of the feature that would resolve your issue.

I would like to be able to scale the recipe and then save it. Another option is to remember the last scale and re-scale to it when loading a recipe.

Please consider and list out some caveats or tradeoffs made in your design decision

I would prefer to be able to easily scale then save the recipe. Sometimes the steps need modification too so scaling ingredients, tweaking the steps then saving seems like the better long term option to me.

I don't really know Typescript so would probably not be a good candidate for implementing this but if I had some good hints what needs to be done and/or examples I'd give it a shot.
