"You have reached the number of custom domains" after changing my singe domain name

### 👟 Reproduction steps 1. Make sure you are on free plan 2. Go to settings there add a custom domain 3. Type any domain name 4. Press "Add" 5. The verification DNS records will appear this time 6. Now press the "Change" button 7. Change your domain name to something else 8. Press "Add" again ### 👍 Expected behavior It should let me change the domain name. ### 👎 Actual Behavior To me it shows "You have reached the number of custom domains" even if my old domain isn't there anymore. I'm currently entirely locked out from creating new domains, everywhere it shows "You have reached the number of custom domains" even if I haven't got any domains anywhere. https://github.com/user-attachments/assets/895302fd-dda0-4980-9b03-d4763dc0c634 ### 🎲 Appwrite version Appwrite Cloud ### 💻 Operating system MacOS ### 🧱 Your Environment Don't think it's super relevant here, I'm on appwrite cloud console and that's where the issue is. ### 👀 Have you spent some time to check if this issue has been raised before? - [x] I checked and didn't find similar issue ### 🏢 Have you read the Code of Conduct? - [x] I have read the [Code of Conduct](https://github.com/appwrite/.github/blob/main/CODE_OF_CONDUCT.md)
