FEATURE: Integration Tests

[CesarD]

Detailed Description

Create a new testing project for performing integration tests of the application

Context

So far Monaco counts with almost all kind of unit tests: for domain entities, for validators, for commands and queries handlers, architecture tests, but it still lacks integration tests to test end-to-end behavior of the application, which would greatly improve testing the stability of the system for the most common scenarios.

Possible Implementation

The idea is to leverage TestContainers to provision the infrastructure necessary for running the app on a developer environment and test its features systematically with disposable containers.
