@elias-ba well done 👏 this was a massive set of changes... It's looking great, excited for the rest of them to match the new stuff!

I have some comments on prefixing the fields name to all the error messages. So not rejecting right now - but I think we can solve it a little differently.

Hey @stuartc and @NickOpenFn this is looking now much better. I have introduced usage of gettext to translate Ecto errors to more humanized errors. Let me know if you need anymore change.
