Migrate all models into schema.prisma

Implementation description

• Defined the prisma models in schema.prisma
• Set up the database connection (env's in slack)
• Installed prisma dependencies
• Applied initial migration

Steps to test

1. cd into the starter-code-cli repository and run npm run dev -- --testing
2. select (PERN and opt-in to all features) and clone from cynthia/migrate-models-to-prisma
3. add the .env files in the root, frontend/, and backend/typescript/models/primsa/
4. run docker exec -it scv2_ts_backend bash and cd into models/prisma
5. run npx prisma migrate status , if the initial migration has not been applied yet run npx prisma migrate dev --name init
6. runnpx prisma studio
7. verify that the tables are loaded at http://localhost:5555/

What should reviewers focus on?

• please also skim over the models and ensure they are the same as the sequelize models
• when I introspected the database it automatically created the "created at" and "updated at" fields - do we want to keep these or not?
