feat(cms): add maintained user guide with Súgó menu entry
- docs/felhasznaloi-utmutato.md: user guide for the website and the CMS
  (login, editing, arrays, save/validation, publish, security)
- /guide endpoint renders the markdown auth-protected via a dependency-free
  renderer (scripts/markdown-render.js) in the CMS dark theme
- new  Súgó entry in the CMS bottom bar
- steering rule: the guide must be updated in the same commit as any CMS or
  website feature change

Closes MITHOME-57
