use new URL in subscribeSafariPromptPermission

Due to changes in our API, the `appId` is now required in the URL
used by `subscribeSafariPromptPermission`. In instances where the new
URL is not usable, we fallback to the legacy URL with an additional
request. This ensures compatibility with both the updated and legacy
API endpoints.
