feat: expand shop menu for improved UX

[Sushil010]

Summary

Added expandable functionality to the Shop Menu component to improve category navigation and overall UX.

@Sushil010, great work! But please exclude package.json and package-lock.json files from your PR, and resolve conflicts in 'MainHeader' component please.

@Alexandrbig1 Hi! I’ve resolved all merge conflicts and rebased the branch with the latest main. Everything looks good and is working as expected now. Please review the changes when you get a chance. Thank you!

@Sushil010, great work on expanding the Shop Menu — it looks really good!
Before merging, please move the Shop Menu code out of the main Header file and into its own component for better structure.

Example:

• Create a new folder: components/ShopMenu/
• Add the menu code there (can split into smaller files if needed)
• Import <ShopMenu /> into the Header

This will make the codebase more modular and easier to maintain. Awesome progress!
