feat(flows): add update_scrum4me_web flow and UI page

- Update ops-agent/flows.example/update_scrum4me_web.yml with full
  deployment steps: git_status, git_fetch, git_log_ahead, git_pull,
  npm_ci, prisma_migrate_deploy, npm_run_build, systemctl_restart,
  and smoke test against thuis.jp-visser.nl/api/products
- Add npm_ci, prisma_migrate_deploy, npm_run_build, and
  curl_smoke_scrum4me_thuis to commands.yml.example
- Add /flows/update-scrum4me-web UI page with Run and Dry Run buttons,
  streaming terminal output, and link to audit log on completion
