The PostgreSQL service in the GitHub Actions workflow was replaced by a Docker container for better control and flexibility. Additional steps were added to manage the container lifecycle, including starting, logging, and cleaning up. Also, updated the app version from 0.2.4 to 0.2.5.
This change introduces a step in the e2e API smoke workflow to wait for PostgreSQL readiness before executing further steps. It retries the connection multiple times to ensure the database is available, reducing potential errors caused by service unavailability.
This commit introduces a GitHub Actions workflow for running E2E API smoke tests on main branches and pull requests. It includes a test suite covering authentication, CRUD operations, metrics access, and alerts status. The README is updated with instructions for running the tests locally.
