Review build-jobsync-container, refine docs-preview tooling

- Review build-jobsync-container.md: fix nonexistent `mirror-sync` task
  reference (Forgejo mirrors sync automatically), mark reviewed
- Remove bat hint from docs-review checklist (output not visible in
  agent sessions), keep docs-preview hint as user-facing step
- Simplify review-documentation.md visual preview section
- Fix Python 3.14 tarfile deprecation warning in docs-preview
