Improve Signup Process with Email Verification and Page Redirection

[lokeshwar777]

Description

This PR introduces a secure email verification process during user signup and implements page redirection after successful verification. The key changes include:

• Email Verification: Users now receive a verification email with a link that must be clicked to activate their account.
• Page Redirection: Users are redirected to login page after the verification link is sent to their email instead of retaining them on the signup page.

Related Issue

This PR addresses the need for a secure verification process during user signup to enhance platform security and improve user trust.
Closes #151

Motivation and Context

The signup process previously lacked a secure verification step, leading to potential security vulnerabilities. Implementing email verification ensures that user accounts are authentic and verified, adding a layer of security and preventing unauthorized access. Page redirection to login page improves user experience by confirming the successful completion of the signup process.

How Has This Been Tested?

The changes have been tested locally by signing up with different email accounts, ensuring the verification email is sent and the account is activated only after clicking the link.
