Subject: [PATCH 13/28] fix: use body-file for PR creation and add flake inputs
 to summary

Fix empty PR summary caused by backticks being interpreted as command
substitution when expanded via ${{ }} in shell context. Add dedicated
flake inputs section showing nixpkgs and flake-utils revision changes.

Subject: [PATCH 17/28] fix: use PAT token in auto-update workflow to trigger
 CI

GitHub Actions events created with GITHUB_TOKEN do not trigger other
workflows. Switch to a PAT so that PRs created by auto-update properly
trigger the CI workflow.
