Nestjs rewrite

**As part of this PR the following has been completed:**

- Rewrote the entire project in NestJS

- Reworked the structure of the project to make it easier to identify key areas. With each new section there are various README files which discuss the section.

- Added various unit tests with Vitest to cover all the pieces of functionality with the help of Cursor

- The project is now type safe, all response interfaces are generated from the Graphql schema. Every other interface is manually maintained as the data is from The Open Movie Database's systems OR the desired types couldn't be automated.

- Any environment variables required are now validated via Joi (Would have used zod but couldn't OR you have to do a lot of work just to get it to work)

- Updated the github actions to use yarn latest version.

- Added a "Discover" module to allow users to quickly search for shows or movies, for now this just mimics what the The Open Movie Database discover page is doing. There still some work that needs doing about this, currently it fetches one one page at a time to get this working at the UI layer it'll need to use an infinite query
