Currently, when a user enters an incorrect Aadhaar number or wrong OTP during ABHA generation, there is no proper pop-up notification to indicate the error. This creates confusion as users are unaware of what went wrong. A clear error pop-up should be displayed to guide users on the issue.

Steps to Reproduce:

1. Navigate to the ABHA Generation section.
2. Enter an incorrect Aadhaar number and attempt to proceed.
3. Observe that no clear pop-up message is displayed.
4. Enter an incorrect OTP and submit.
5. Observe that no pop-up appears to indicate the OTP error.

Expected Result:

• When a wrong Aadhaar number is entered, a pop-up should appear with a clear message (e.g., "Invalid Aadhaar number. Please enter a valid 12-digit Aadhaar.").
• When a wrong OTP is entered, a pop-up should notify the user (e.g., "Incorrect OTP. Please try again.").

Actual Result:

• No clear pop-up message is displayed.
• Users are unaware of the issue unless they manually check the fields again.
