Fix UI of the game

[AyeshaShahid10]

This PR improves the overall UI/UX of the Word Puzzle game.

🔹 Changes Made

Navbar: Improved styling for better visibility and cleaner look.

Cells: Enhanced structure and added logic so that when a correct word is entered, the cells change color to green (clear visual feedback).

Buttons: Redesigned with a more visible and attractive style to improve user interaction.

🎯 Why

These changes make the game more user-friendly, intuitive, and visually appealing, helping players focus on gameplay without UI distractions.

Feel free to contact me about improvements or any further changes.

@AyeshaShahid10 Hi, thanks for your help. Sorry for the delay, I'll be reviewing your contribution this week. Have a nice day.

I've reviewed your changes and I think they're beautiful! I just ask you to fix the print button (I think it's not working) and same with Configuration button. They both don't do nothing when I click them. What's more, I see Configuration panel at the bottom of the page. It should be loaded as a modal, when I click on "Configuration" button.
I'll reassign this to you, in order to improve this points.
Keep up the good work.

Thanks for the thoughtful review and kind words!
You’re absolutely right about the print and configuration buttons I’ll go ahead and fix their functionality and make sure the configuration panel opens as a proper modal instead of showing at the bottom.
I’ll push an update shortly to address these points. Really appreciate your feedback and guidance!
