"""Insère le nouveau contenu guide #105 dans frontend/index.html.

- 8 nouvelles sections + entrées de TOC (guide_content.py)
- compléments h3 dans 5 sections existantes
- BUG-067 : le bloc « Édition mobile » de help-edition devient la section
  dédiée help-mobile-editor (ancre morte → ancre vivante)
- retire l'attribut data-i18n-placeholder dupliqué sur #help-nav-search

Idempotent : refuse de tourner deux fois (détecte guide105.* déjà présent).
Préserve les fins de ligne CRLF de index.html.
