As already mentioned in your stack overflow link, you should use the the backend. In your case "1" do you hide the edit server side (Delphi code)? Then you can there also save it server side! Maybe you can also encrypt the value or build a hash code you check later on server side. I think there is no other solution...

How? -> save server side!

see https://docs.devart.com/sdac/faq.htm: Are the SDAC connection components thread-safe? Yes, SDAC is thread-safe but there is a restriction. But the same TCustomMSConnection object descendant cannot be used in several threads. So if you have a multithreaded application, you should have a TCustomMSConnection object descendant for each thread that uses SDAC

If you have the target server under control, then you can configure CORS there...
