feat(content): v4.6.0 Content Blocks enrichis — Callout, TOC, Math (KaTeX), Toggle, Multi-colonnes

- Ajout blocs enrichis dans l'éditeur: callout (avec sélecteur d'emoji), table of contents (ancres), math (LaTeX/KaTeX), toggle lists (enfants collapsibles), multi-colonnes
- Intégration KaTeX 0.16.11 self-hosté (JS/CSS/fonts) — aucun CDN externe
- Rendu des nouveaux blocs dans les pages publiques (/p/<slug>): TOC, KaTeX, colonnes, toggle <details>
- Persistance 'children' (colonnes/toggle) + export Markdown étendu
- Sidebar customization par utilisateur (config API + colonne sidebar_config)
- Correctif test_views_calendar: parsing des query params year/month (le défaut ouvrait sur le mois courant)
- Tests: 184 passing
