/**
 * DC-171 phase 2 — wizard-to-adapter PowerDNS configuration integration.
 *
 * The setup wizard saves the generic shape { provider, ip, port, token }
 * (plus provider-specific aliases since batch 9 r5). This test feeds a
 * wizard-shaped siteConfig through the REAL createProviderDnsContext
 * factory and asserts the resulting PowerDNS adapter is fully configured
 * (server, API port, key) and authenticates against a mock PowerDNS API —
 * the exact gap judge r5 flagged (builder read dns.server/apiPort/apiToken
 * while the wizard wrote dns.ip/port/token).
