feat(opeanpi): Generate openapi scema dynamically on app startup.

This version doesn't seem to compile on Docker, as there is no java installed, so I can not merge this as-is (the master branch cannot have anything that would crash an existing backend on automatic update).

I modified the Dockerfile to install openjdk17 from Alpine Linux's repositories and it seemed to work fine. However I'm not certainly sure whether we should install java on the primary docker file; it increases the size of the production image a lot.

In other words, as much as I respect your will to contribute to this project I'm not going to merge this PR as long as the functionality is not separated from the actual API-server.

Could the generator script be instead manually ran on development machines?

No, as the whole purpose of it is to dynamically use environment variables to match the deployment which shouldn't/cannot be done anywhere else easily than runtime meaning that doing it in Docker's build stage is also not something that would satisfy that need.
