fix(ci): replace GitHub Actions with native bash commands

- Remove dependency on GitHub (network blocks access)
- Replace actions/checkout@v4 with git clone
- Replace actions/setup-python@v4 with apt-get install
- Replace docker/build-push-action with native docker commands
- Use config.settings.test (SQLite in-memory) for tests

Closes: network connectivity issue in CI
