Middlewares

1. verifyToken
   This middleware ensures secure access by verifying JWT tokens from the request's cookies or headers. It decodes the token, retrieves the user from the database, and attaches the user object to the req object. Unauthorized requests are blocked with appropriate error handling.

2. upload
   A Multer-based middleware to handle file uploads. It stores uploaded files in the ./public/uploads directory and appends a timestamp to the original filename to ensure uniqueness.
