Added Resend Email Verification and Delete Unverified Users after 24 Hours

[IkkiOcean]

This PR introduces two major features:

1. Resend Email Verification: Users who haven't verified their accounts can now request to resend the email verification link.
2. Delete Unverified Users: A scheduled task that deletes users who have not verified their account within 24 hours of registration.

Key Changes:

Backend Changes:

1. User Schema Update:

   • A new field timestamps has been added to the user schema to track the timestamp of when the account was added.

2. New Routes:

   • A route has been added to allow users to request the resending of the email verification link.

3. UserController Updates:

   • Logic has been implemented in the UserController to handle the resending of verification emails, ensuring that the email is only resent after a 24-hour period has passed.
   • A scheduled task using a cron job has been added to delete unverified users who have not verified their account within 24 hours.

Frontend Changes:

1. Resend Email Verification Page:

   • A new page has been created on the frontend where users can request to resend the verification email if they have not received it or if the link has expired.

2. Resend Button:

   • A UI button has been added to trigger the request for the verification email to be resent.

Summary of Changes:

1. Backend:

   • Updated the user schema to track the email resend timestamp.
   • Created routes for resending email verification links.
   • Implemented functionality for deleting unverified users after 24 hours.
   • Cron job added to automatically delete unverified users at midnight every day.

2. Frontend:

   • Added a page for users to request a new verification email.
   • Added functionality to handle user input and communicate with the backend to resend the email.

This PR aims to improve user experience by allowing users to request the resend of verification emails, and also ensures that unverified users are automatically cleaned up after 24 hours, enhancing overall system efficiency. Let me know if further changes or improvements are needed.

How should this be tested?

1. try signup and do no verify with the first email, instead click on the resend verification email button for new link
2. during the start of backend, the terminal will log the start of deletion job

note: I have used timer of 10 sec in video to show resend email verification functionality, but its 2 min in real to prevent email spam.
