API error message displayed to user during phone number verification

Describe the bug
When entering an OTP for phone number verification from the Profile section, a backend error message is shown to the user:
Unknown argument "otp" on field "Mutation.sendOtpToPhoneNumber".
This indicates that the API request payload does not match the backend schema, and the error is not being handled gracefully.

To Reproduce
Steps to reproduce the behavior:

Go to Profile.
Add a phone number and request OTP verification.
Enter the OTP.
Observe the error message displayed in grey over the OTP input area.
Expected behavior

The API request should accept the correct parameters and successfully verify the OTP.
If an error occurs, display a user-friendly message (e.g., "Invalid OTP, please try again.") instead of backend error text.

Start in the Profile phone-number verification flow and trace the request sent when the OTP is submitted, focusing on the Mutation.sendOtpToPhoneNumber call and its error handling. Confirm the payload matches the backend schema, then reproduce the flow to verify successful verification and a user-friendly message for an invalid OTP.
