docs: add all missing pages to mkdocs nav and fix absolute link

- Add 32 pages to nav: architecture (9), modules (1), migrations (1),
  testing (3), proposals (8), archive (11)
- Fix absolute link in jinja-macros.md that mkdocs couldn't validate
- Exclude mkdocs.yml from check-yaml hook (uses !!python/name tags)
- Result: mkdocs build with zero warnings
