feat: Add GitHub Actions workflow to run stack

This commit introduces a new GitHub Actions workflow (`.github/workflows/run_in_action.yml`).

The workflow allows for running the entire application stack (API, Redis, PostgreSQL) using Docker Compose directly within the GitHub Actions runner. This is intended for temporary testing or preview purposes.

Key features of the workflow:
- Triggers: Manually (`workflow_dispatch`) or on pull requests targeting `main` or `develop` branches.
- Services: Starts services defined in `docker-compose.yaml`.
- Health Check: Includes a step to wait for services to initialize and then pings the API's root endpoint (/) to verify it's responsive.
- Cleanup: Ensures `docker-compose down` is executed at the end of the run, even if previous steps fail, to clean up resources.
