Issue: Add Confirm Password Field

Description

The user registration form currently lacks a "Confirm Password" field. This enhancement is needed to allow users to verify their password input and reduce errors caused by typos during registration.

Requirements

• Add a "Confirm Password" field below the existing password field.
• The "Confirm Password" field should compare its value with the "Password" field.
• If the passwords do not match, display an error message and prevent form submission.
• Ensure the feature works with both client-side and server-side validation.

Expected Behavior

• When the user enters a password in both fields and the values match, the form should proceed normally.
• If the passwords do not match, an error message should be shown, and form submission should be blocked until the issue is resolved.

Tasks

• Add "Confirm Password" field to the form.
• Implement validation logic to compare passwords.
• Display appropriate error message when passwords do not match.
• Block form submission if the passwords do not match.
• Add unit tests for the new field and validation logic.

Additional Notes

• Consider accessibility (screen readers should correctly identify the fields and error messages).
• Ensure compatibility with existing form validation logic.
• Test for edge cases, such as empty fields or mismatched passwords during form resubmission.
