Fix scripts: remove duplications, hardcoded credentials, and restore proper workflow

- Remove hardcoded Quay.io credentials from build-and-push.sh
- Create common.sh with shared functions to eliminate duplication
- Create rollout-restart.sh for simple updates (recommended workflow)
- Refactor deploy-complete.sh and rollout-restart.sh to use common functions
- Add comprehensive README.md explaining proper workflow
- Restore correct process: git push -> GitHub Actions -> rollout-restart
- Fix security issues and improve maintainability
