Fix: Add secret to Auth.ts to resolve NextAuth.js NO_SECRET error in production

---

Description

This pull request adds the missing secret to the NextAuth.js configuration in Auth.ts. Without this secret, deploying the application to Vercel or any production environment resulted in the following error:

[next-auth][error][NO_SECRET] 
https://next-auth.js.org/errors#no_secret Please define a secret in production.
Error [MissingSecretError]: Please define a secret in production.

By defining the secret using the NEXTAUTH_SECRET environment variable, this issue is resolved, and the authentication system now functions securely in production.

---

Changes Made

1. Added secret to Auth.ts:

   • The secret is now sourced from the NEXTAUTH_SECRET environment variable.
   • This ensures compliance with NextAuth.js's production security requirements.

2. Resolved Deployment Error:

   • Fixed the error encountered during deployment on Vercel due to the missing secret.

---

Testing Instructions

1. Generate a Secure Secret:
   Use the following command to generate a strong secret:

   openssl rand -base64 32

2. Update Your .env File:
   Add the generated secret to your .env file:

   NEXTAUTH_SECRET=<your-generated-secret>
   

3. Verify Locally:

   • Run the application locally and confirm that authentication works without issues:

     npm run dev

4. Verify on Vercel:

   • Deploy the application to Vercel and ensure the error no longer occurs.
   • Test the authentication flow to confirm it is functioning as expected.
