The push subscription requires an active service worker. When
registering a new service worker, we now wait for it to become
active using navigator.serviceWorker.ready before attempting
to subscribe to push notifications.

When you had already granted notification permission but hadn't
completed the subscription flow (no service worker or no push
subscription), the UI showed neither the subscribe button nor the
enabled state, leaving you stuck with no way to subscribe, and wrong
instructions to fix it.
Instead, let's just show the button to allow you to subscribe.
