Describe the add-ons or changes you've made 📃

Added a back button to the project detail page to allow users to navigate back to the previous page.

Changes made:

• Imported useNavigate hook from react-router-dom and ArrowBackIcon from Material-UI icons
• Added navigate hook inside the Project component
• Created a back button in the header section next to the project title
• Used navigate(-1) to go back to previous page in browser history
• Button uses outlined variant to match the existing design system

Location of changes:

• File: client/src/modules/code/Project.tsx
• Section: Header section where project title is displayed

This solves the issue where users had no way to exit the project page without using browser controls.

Instead of button, use A2ZIconButton

@pratyushjha06 Please update it accordingly

And you don't need to add custom styling in case of A2ZIconButton.
