Improve deployment process and add login redirect logic

Deployment improvements:
- Add template env files (.envs.example/) for documentation
- Create init-production.sh for one-time server setup
- Create build-activepieces.sh for building/deploying AP image
- Update deploy.sh with --deploy-ap flag
- Make custom-pieces-metadata.sql idempotent
- Update DEPLOYMENT.md with comprehensive instructions

Frontend:
- Redirect logged-in business owners from root domain to tenant dashboard
- Redirect logged-in users from /login to /dashboard on their tenant
- Log out customers on wrong subdomain instead of redirecting
