feat: responsive images for investigation template

Add srcsets in config:
- cover-hero: 940px fixe ≥1000px, 90vw en dessous
- body-full: 100vw (1 colonne)
- body-half: 50vw ≥768px, 90vw en dessous (2 colonnes)

Apply in templates/snippets:
- Cover hero → snippet picture + cover-hero
- Body 1-col images → snippet picture + body-full
- Body 2-col images → snippet picture + body-half
- gallery.php → snippet picture (sizes/srcset paramétrables)
- beforeafter.php → srcset/sizes sur <img> (pas de <picture> pour ne pas
  casser le JS du slider)
