fix(ci): Corriger les tests E2E en CI

Plusieurs problèmes empêchaient les tests E2E de passer en CI :

1. Healthcheck : L'endpoint /api nécessite une authentification et
   retournait 401, causant l'échec du healthcheck. Remplacé par
   /api/docs qui est public.

2. Mailer : L'activation de compte déclenche l'envoi d'un email via
   mailpit, qui n'est pas disponible en CI. Ajout d'une variable
   d'environnement MAILER_DSN=null://null pour désactiver l'envoi.

3. Token partagé : Chaque navigateur (chromium, firefox, webkit)
   consommait le même token, causant des échecs pour les suivants.
   Maintenant chaque navigateur crée son propre token dans beforeAll
   avec un email unique (e2e-{browser}@example.com).

4. Nettoyage : Suppression de test-utils.ts et global-setup simplifié
   car la création de token est maintenant dans le fichier de test.
