ci/cd: gains typical GH action checks

[jdhoffa]

We will want to set up automated CI/CD checks in GitHub Actions to ensure code quality, security, and reliability. These checks will help enforce best practices and provide early detection of issues.

Essential checks:

• Unit Tests
• Test coverage
• Linting (black? pep8?)
• Dependency security audit

Stretch goals (we may or may want to implement these):

• Type checking
• Docker build and integration check (eventually)
• Deployment check (e.g. automate pushing to Azure Container Registry)
• API contract validation (e.g. OpenAPI spec validator)

Later considerations:

• Deploy to Azure from main
• Performance testing (e.g. locust or k6)
• Secrets scanning (e.g. truffleHog or gitleaks)

Note: We likely will eventually want to migrate these to https://github.com/RMI-PACTA/actions for portability across otherpython projects.

Unit (and integration) tests have been handled in #12
