Update staging configuration to avoid port conflicts and enhance deployment scripts

- Changed staging app port from 3001 to 3002 in docker-compose.staging.yml
- Updated PostgreSQL port from 5433 to 5434 and Redis port from 6380 to 6381
- Modified STAGING_SETUP.md to reflect new port configurations
- Adjusted CI/CD workflows to accommodate new staging ports and improve deployment messages
- Added N8N environment variables to staging configuration for better integration
