AuthenticationServiceFactory

Factory that creates the appropriate AuthenticationService based on configuration.

Reads auth_provider and env from ZIO Config to determine which authentication implementation to use:

• "test": TestAuthenticationService (for testing only, forbidden in production)
• "oidc": Pac4jAuthenticationAdapter (for production OIDC authentication)

Example usage:

 val app = ZIO.serviceWithZIO[AuthenticationService](_.currentUser)
   .provide(AuthenticationServiceFactory.layer)
