Missing Database Connection Validation in Workflows

Files: .github/workflows/cd_dev.yaml, .github/workflows/cd_prod.yaml

Issue: Workflows create .env from secrets but don't validate database connectivity before running tests. Tests may fail due to network issues rather than code issues.

Recommendation:

Add a pre-test step that validates database connections
Provide clear error messages if databases are unreachable
Consider using GitHub Actions services for test databases

Start by reading .github/workflows/cd_dev.yaml and .github/workflows/cd_prod.yaml, focusing on how .env files are created and where tests run. Compare the two workflows and identify the existing database configuration; done means both workflows check database reachability before tests and report a clear error when a connection cannot be established.
