Severity: Medium

1. Allows incomplete user profiles, which may affect data integrity or downstream systems relying on full names.
2. Does not expose sensitive data or allow unauthorized access.

Describe the bug
The Profile Settings form on app.aixblock.io allows users to save their profile without providing a last name, which violates the expected validation rules.

To Reproduce
Steps to reproduce the behavior:
1.Navigate to https://app.aixblock.io/ and log in.
2.Go to Profile Settings (e.g., https://app.aixblock.io/user/account).
3.Leave the Last Name field empty.
4.Click Save Changes.
5.Observe that the form saves successfully without requiring a last name.
Expected behavior
The Last Name field should be marked as required, and the form should reject submission if it’s empty.

Additional context

1. This issue may affect user data consistency in systems that rely on full names (e.g., customer support, analytics).
2. Consider adding an error message like: "Last name is required" to guide users
