Add production deploy workflow and PM2 config

Introduce a GitHub Actions CD workflow (.github/workflows/cd_prod.yml) that runs tests on push to main and deploys to the production server (vlcdhprdp01). The workflow sets up Node.js, caches npm, runs tests, then checks out the repo on the target host, ensures log files exist, pulls latest code, installs deps, manages the app with PM2, and performs a health check. Add ecosystem.config.js with a PM2 app definition for 'inbox' including development and production environment variables (production MongoDB URL and other settings).
