Issue Description:

[Chore] Replace findViewById() with ViewBinding

Problem:
The app currently uses findViewById() to reference UI elements, which is boilerplate-heavy, prone to NullPointerExceptions, and less efficient compared to ViewBinding. Migrating to ViewBinding will improve code readability, performance, and type safety.

Expected Solution:

• Enable ViewBinding in the project by updating the build.gradle file.
• Replace all instances of findViewById() with ViewBinding.
• Ensure proper lifecycle handling of binding instances to avoid memory leaks.

Steps to Implement:

1. Enable ViewBinding in build.gradle:

   android {
       viewBinding {
           enable = true
       }
   }

2. Replace findViewById() in activities, fragments, and adapters with ViewBinding.
3. Use proper lifecycle management for binding in fragments to avoid memory leaks.

Acceptance Criteria:

• All findViewById() references are replaced with ViewBinding.
• UI interactions remain fully functional after the migration.
• Proper lifecycle management is followed in fragments and adapters.

Let me know if you need code examples for the migration! 🚀
