feat: add automatic client SDK generation

[eric-nguyen-cs]

What

• Add an automatic client SDK generator: it uses the fact that we are able to export an OpenAPI spec from FastAPI and that this spec is able to be parsed into a Typescript client

The goal is in the future to incrementally add Pydantic Models as return types to the path functions to serve as output validators and as documentation for the OpenAPI spec.
Thus, adding a new API call on the frontend should now involves:

• adding a Pydantic model to the return type of the API call
• using the client SDK to call the RPC instead of manually calling the API using fetch or axios. The API return types should also be imported from the SDK

Good work, I approve! I have a question though

[alexgarel]

Do you really want to put it in the git ?

Why not generate it with fastapi instead ?

[eric-nguyen-cs]

🤔 Well I found it was easier to implement this way (and it may also facilitate the debugging of the SDK generation)
If you want I can have a look at how to do the FastAPI server but I feel that it may be a bit complex (namely what happens if the server is already running)
