Add dev2 deploy automation

[aditya-damerla128]

Summary

• reuse the existing refserver and landing deploy workflows for dev pushes
• add dev2 deploy jobs for both refserver and landing using direct SSH/rsync
• preserve dev2's current /home/adamerla/ozwellai-api + PM2 + local .env shape while deploying build artifacts
• make the landing manager URL environment-driven so dev2 can use ozwellconsole without dirty tracked files
• include root workspace manifests in the refserver deploy package so remote installs can use the root lockfile

Validation

• git diff --check
• bash -n scripts/build-deploy-package.sh scripts/build-demo-package.sh
• node --check landing-page/server.js
• workflow YAML parse

Fixes #234

Pull request overview

This PR extends the existing production deploy automation to also deploy on dev branch pushes (targeting the dev2 environment), and makes the landing page “Ozwell Manager” URL configurable via environment variables to avoid environment-specific tracked-file changes.

Changes:

• Add dev branch triggers and branch-scoped concurrency for the reference-server and demo-site deploy workflows, and split deploy jobs into deploy-prod vs deploy-dev.
• Implement dev2 deploy steps using direct SSH + rsync, preserving dev2’s /home/adamerla/ozwellai-api + PM2 + local .env shape.
• Make the landing page manager URL environment-driven by injecting MANAGER_URL into HTML at serve time and using it for legacy redirects.
