fix: Enable automatic Docker workflow triggering with PAT token

- Replace GITHUB_TOKEN with PAT in auto-version workflow to allow triggering subsequent workflows
- Improve Docker workflow README update logic to handle repository_dispatch events properly
- Add support for manual Docker builds with latest tag updates
- Fix condition logic for when to update README.md documentation

This resolves the issue where fix: prefixed PRs created tags but didn't trigger Docker builds,
ensuring complete automation flow from PR merge → version bump → Docker build → README update.
