NOTIFY_URL is a global platform credential; NOTIFY_API_KEY is project-
scoped and may not be provisioned if notify setup failed or the
notifyProvisioner wasn't configured. Previously the service would crash
on startup with "invalid configuration: API key is required" when
NOTIFY_URL was set but NOTIFY_API_KEY was missing.
Now the condition checks both: only initialize the notify client when
both NOTIFY_URL and NOTIFY_API_KEY are set. When either is absent, fall
back to log-only mode with a warning (instead of os.Exit(1)).
This is the correct behavior: email not delivered is survivable, but a
service crash on startup breaks the entire application.
