Setup Automated API testing!!!

[rawanmahdi]

Ideas:

• Taking the github actions approach, and using the fastapi testing client to generate tests, then call them through pytest and a github workflow that runs after every PR for the backend folder. See this example.
• Or a way cooler idea: setup a jenkins pipeline! this will be harder/kind of overkill but a good new framework to pick up!

(if we need more tickets we'll do both for fun :) )
