Where to place and how to access server side required files for consistent access in dx serve and dx build?

[yanshay]

In a full-stack application, I need to access files on the server side to use at runtime.

• I want to be able to access those files from server side code.
• I don't want those files to be accessible by the client (so can't be in the assets folder).
• I want dx build to copy them from the project folder to the proper location
• I want the files to be accessible both when doing dx serve and from the execution of the outputs of dx build in the same way.

What's the right way to do that with dioxus?
