Setup docker for production and development

Change ./init.sh to be an executable then run it.

The default inner container ports are as followed:
- Postgres: 5432:5432
- Backend: 3001:3000
- Frontend: 3000:3000

- Frontend dev: 8000

The backend image needs to be built:

docker compose up -d --build

frontend/.dockerignore
