Refactor Popular Monuments View Mobile ✅

[kareemabdeen]

##Describtion
This refactor simplifies and modularizes the PopularMonumentsViewMobile by extracting reusable components and improving readability. The grid view logic has been moved into a separate widget, making the codebase easier to maintain and test while keeping functionality intact.

Key Changes:

. Modularized Components:

• Extracted the grid view logic into a dedicated PopularMonumentsGridViewWidget.
• Made PopularMonumentsViewMobileBodyBlocBuilder more focused on managing state transitions and delegating UI logic to sub-widgets.

Motivation:

These changes aim to enhance app performance, simplify testing, and improve the maintainability of the codebase. The modular structure also promotes reusability of components across different views or contexts in the future insha2allah.
