Resolves

Implements automated email alerts for failed CI pipeline runs.

Changes

Modified the GitHub Actions workflow to ensure build failures are reported to the team immediately:

• Workflow Reliability: Added if: always() to the notifications job to prevent it from being skipped when the testing job fails.
• SMTP Integration: Replaced placeholder echo statements with the dawidd6/action-send-mail@v3 action for formal email delivery.
• Contextual Notifications: Configured the email body to dynamically include the repository name, branch name, commit SHA, and a direct link to the failed logs for faster debugging.
• Security & Variables: Added server and recipient configurations to GitHub Variables and used Secrets for the SMTP password to maintain security best practices.

Testing

• Simulated Failure: Triggered the workflow with a failing test case to verify the notifications job executes as expected.
• Metadata Accuracy: Confirmed the email body correctly renders ${{ github.ref_name }} and ${{ github.run_id }} for precise log linking.
• Conditional Check: Verified that emails are only dispatched when the python-unit-tests job result is specifically 'failure'.
