feat: add email verification confirmation screen with resend option after registration

[pericharlabindhumadhavi-data]

Closes #243

What was the problem?

After successful registration, users were instructed to verify their email address. However, if the verification email was delayed, filtered as spam, or entered incorrectly, there was no way to request another verification email from the application.

This left users unable to complete account activation without external assistance.

How was it solved?

• Added a "Resend Verification Email" option to the post-registration flow.
• Integrated the resend verification API endpoint.
• Provided a straightforward recovery path when verification emails are not received.

Impact

• Improves onboarding experience for new users.
• Reduces user frustration caused by missing verification emails.
• Increases successful account activation rates.

Checklist

• Added resend verification email functionality.
• Integrated appropriate API call.
• Tested resend email workflow.
• Followed CONTRIBUTING.md guidelines.
