Unable to Create a New Queue Subscription After Deleting the Previous One

First, I created a queue subscription through the UI.

After deleting the subscription, I tried to create a new one, but it fails with the following error:

> We currently do not support multiple subscriptions on the same resource.

I also tried creating the subscription using the CLI:

```bash
pnpm dlx wrangler queues subscription create my-queue --source r2 --events bucket.created
```

However, I get the same error from both the UI and CLI.

I'm not sure how to resolve this or whether the previous subscription is still being retained somewhere after deletion. Any help would be appreciated.

Reproduce the failure with the Wrangler command shown in the issue, then compare it with the UI flow after deleting the original subscription. Trace how queue subscription deletion is recorded and verify that creating a replacement subscription for the same R2 resource succeeds without the multiple-subscriptions error.
