Server general functionality

The concept of the server is for 3 tasks:
1. storing and providing the code snippets to the client
2. managing and moderating safe code
3. Optional - compiling code on the server and providing the client with a websocket connecting to the compiled code until termination.

Would love to hear your ideas for more options and functionality, and how would you suggest to implement the current ideas based on the outline of the server

The issue names no file, test, or entry point. First clarify and document the agreed server requirements for snippet storage, safety moderation, and optional compilation/websocket behavior; done means the scope and implementation plan are accepted.
