Reworking Dockerfile, CI, NPM Scripts

[Kawanaao]

In this pull request I want to change the scripts for development, debugging and publishing, for now the goal is

• [x] Minimize the size of the output container while maintaining functionality
• [x] Caching
• [ ] Rewriting Circle CI for new Dockerfiles
• [x] Adding generalized scripts to NPM, including content generators (Halfway with generators)
• [ ] Adding Github Workflows files or at least integration with Circle CI, for PR validation

I think maybe it’s worth transferring the meta data according to the principles of OpenContainers Annotations? Instead of meta.json

Hey, it may be worthy to utilise https://github.com/air-verse/air for running dev version of the server by default. I can see myself making multiple changes and then having to restart the build and restart server right now Let me know about your thoughts on this @Kawanaao

I can see that this has not been updated since the last 2 months. I can take over if @Kawanaao or @azukaar agrees.
