URGENT! Missing required attribute "emailCanonical" After update to 1.9.0

### 👟 Reproduction steps Upgrade Appwrite from an older version (e.g. 1.8.x) to 1.9.0 using Docker Do not run or fail to complete appwrite migrate (migration fails or partially runs) Open Appwrite Console or use SDK Attempt to create a new user (email + password) Observe error during user creation ### 👍 Expected behavior User should be created successfully, with all required attributes automatically handled by Appwrite (including emailCanonical). ### 👎 Actual Behavior Missing required attribute "emailCanonical" In some cases also appears as: Attribute not found: emailCanonical Invalid document structure: emailCanonical ### 🎲 Appwrite version Version 1.8.x ### 💻 Operating system Linux ### 🧱 Your Environment Your Environment Self-hosted Appwrite via Docker Compose Upgrade performed from older version (1.8.x) to 1.9.0 Migration attempted but initially failed due to infrastructure issues (DNS / Redis / disk full) After system recovery, migration state appears inconsistent Using Appwrite Console + SDK (React Native / Web) ### 👀 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)
