Add Frontend for Login and Signup Pages with Navbar Integration

[Kashish23092004]

I would like to work on creating the frontend UI for Login and Signup pages. This task includes:

✨ Designing Login and Signup pages using React

🔗 Adding Login and Signup buttons in the navbar

🧭 Setting up basic routing so that clicking these buttons navigates to the respective pages

💻 Keeping the UI consistent with the current theme and layout

This is strictly frontend only — no backend or authentication logic will be handled in this task.

Please assign me this issue if it’s available. I’ll share before-and-after screenshots for clarity once done.
