Pagination : un seul composant partagé pour les trois pages

La logique était triplicée à l'identique dans Documents, Recent Updates et
Ingredient Search, mais chaque page portait son propre style — d'où trois
rendus différents :

- IngredientSearchPage.module.css ne contenait AUCUNE classe de pagination :
  styles.pagination et consorts valaient undefined, les boutons s'affichaient
  donc entièrement sans style. C'est l'écart que tu voyais.
- DocumentsPage : règle .paginationButton malformée, un .ellipsis imbriqué
  dedans par accident de copier-coller.
- RecentUpdates : ni .ellipsis ni dimensions sur les numéros de page.

Un composant components/Pagination.tsx porte désormais la fenêtre de numéros
(extrémités toujours atteignables) et styles/Pagination.module.css le style
unique, sur l'accent bleu #2563eb du site — celui des boutons primaires, 22
occurrences contre 11 pour le violet. Les classes locales devenues mortes sont
supprimées des trois feuilles pour qu'aucun style divergent ne subsiste.

Libellés Previous/Next conservés : les pages publiques sont en anglais.

Vérifié au navigateur : même classe de module, même fond actif rgb(37,99,235),
mêmes dimensions sur les trois pages ; aucun débordement de 320 à 1280px, la
pagination passant à la ligne sous 768px.
