Linting and Formatting for the backend

[hiimchrislim]

Describe the solution you'd like

We currently only have linting and formatting set up for the client. Refer to it as an example.
Additionally, a Github action should be made for it as well to run on each PR

Additionally update husky to run pre-commit linting for backend as well
