[Feat] 🚀 Issue: Seller Login Implementation – Frontend & Backend

[ShivanshPlays]

Description

📝 Description

This issue tracks the complete implementation of the Seller Login functionality, covering both frontend pages and backend logic. The seller login will follow a secure OTP-based email verification process to ensure valid login.

---

📌 Key Objectives

1. Frontend Pages and Forms

   • Create the Seller Login Form to collect the seller's email.
   • Upon form submission, make a request to the backend to generate an OTP and send it to the provided email address.
   • Implement a second form to input the OTP received via email for verification.
   • Ensure smooth user experience with appropriate success and error messages.

2. OTP-based Email Verification

   • Generate a 6-digit OTP and send it to the seller’s email upon login request.
   • Create a reusable email utility function to handle OTP email sending using Nodemailer.
   • Ensure proper error handling for email delivery issues (e.g., invalid email or delivery failure).

3. Backend Server Actions

   • Implement server-side logic to handle the OTP generation and verification process.
   • Develop API routes to:
     • Send an OTP to the email address after login is requested.
     • Verify the OTP submitted by the user.
     • Establish a session if the OTP verification is successful.
   • Handle edge cases (e.g., expired OTPs, incorrect OTPs).
