feat: Permettre au super admin de se connecter et accéder à son dashboard

Le super admin (table super_admins, master DB) ne pouvait pas se connecter
via /api/login car ce firewall n'utilisait que le provider tenant. De même,
le JWT n'était pas enrichi pour les super admins, l'endpoint /api/me/roles
les rejetait, et le frontend redirigeait systématiquement vers /dashboard.

Un chain provider (super_admin + tenant) résout l'authentification,
le JwtPayloadEnricher et MyRolesProvider gèrent désormais les deux types
d'utilisateurs, et le frontend redirige selon le rôle après login.
