Login/sign up - Githubissues

Purpose

I updated the login and signup pages to enhance user experience. Changes include:

Added 'Forgot Password?' functionality to the login page.
Updated the CSS to style new elements and improve form layout.
Replaced the image section in the signup page with a gradient background, adding a heading and subheading to better align with the overall design.
Added split-screen layout to both login & sign-up pages.
