Enatega SingleVendor Admin Allowing Gap in Rider Username and Accepting Negative Values in Phone Number Field

Describe the bug
I have identified two critical issues in the Enatega SingleVendor Admin system within the rider section. Firstly, the system currently allows users to create rider usernames with gaps, potentially leading to confusion and errors. Secondly, the system accepts negative values in the phone number field, which can impact the ability to contact and manage riders effectively.

To Reproduce
Steps to reproduce the behavior:
Issue 1 (Gap in Rider Username):

Log in to the Enatega SingleVendor Admin system.
Navigate to the rider management section.
Create or edit a rider profile.
Attempt to set a username with a gap (e.g., "john doe" instead of "johndoe").
Issue 2 (Negative Value in Phone Number Field):

Log in to the Enatega SingleVendor Admin system.
Navigate to the rider management section.
Create or edit a rider profile.
Attempt to input a negative value in the phone number field.
Expected behavior
Expected Behavior - Issue 1:
The system should validate and restrict users from creating usernames with gaps, ensuring consistency and preventing potential issues with user identification.
