Enatega Admin Dashboard: When adding a new staff and Rider , phone number is added by taking just one digit number

Describe the bug
When attempting to add a new staff member, the phone number input only captures and saves the first digit entered. Also displaying a error message that number is already associated with another account.
Fix it on its update page also
Steps to Reproduce:

Navigate to the "Add New Staff" page.
Fill out all required fields.
Now if user fills the phone number by adding only just one number it accepts it as a full number.
Click on "Save" or "Submit."
Expected behavior
The full phone number (e.g., "1234567890") should be saved and displayed correctly.

Locate the Add New Staff page and its update page in the React admin dashboard, then reproduce the phone-number issue described in the steps. Check how the input value is captured, saved, and validated. Done means full phone numbers are preserved on create and update, while a one-digit value is not accepted or incorrectly reported as an existing account.
