feat(browse): recherche unifiée dossiers + APIs + fix icônes DSFR

- Recherche simultanée dans les dossiers (filtrage client-side) et les
  APIs (backend) via forkJoin — affiche dossiers en tuiles puis APIs en
  cartes, avec labels "Dossiers"/"APIs" si les deux ont des résultats
- Loader instantané dès la frappe (avant le debounce 400ms)
- Fix angular.json : ajout du mapping dist/icons/ → assets/dsfr/icons/
  pour servir les SVG référencés par le CSS DSFR (tous les icônes étaient
  cassés car le chemin relatif ../../icons/ donnait 404)
