[rasouza]

Description

• Add support for OpenAPI
• Add support for Zod validation
• add npm run console to API
• move DB service to global module

Motivation and Context

Steps followed from:

• https://docs.nestjs.com/openapi/introduction
• https://www.npmjs.com/package/nestjs-zod#openapi-swagger-support
• https://docs.nestjs.com/recipes/repl

OpenAPI

So we don't need to maintain Postman/Insomnia collections. It can be acessed through http://localhost:3000/docs

Zod validation

For validating input request payloads

Console

You can live debug and experiment your code. You have access to the main module and all its dependencies at runtime (see image below)
