security (Turnstile, escalating lockout, email verification).

+"""Resolves a NotificationType to a concrete provider. Console is always
+available and never costs anything; email/SMS are only meaningfully
+configured when their settings are present (callers gate on
+NOTIFICATION_SMS_ENABLED before ever routing to SMS - see alert_service.py).
+
+SMS has two interchangeable vendor providers (`SMS_PROVIDER=twilio|telnyx`),
+same pattern as LLM_PROVIDER/SEARCH_PROVIDER elsewhere in the app - swapping
+the setting changes which class this returns and nothing else has to change.
