TITLE

Implement CRUD Functionality for Users in Admin Section

REQUIREMENTS / DESCRIPTION

As an admin, I want to manage users by being able to read, so that I can efficiently manage the user base of the application.

Functionalities:

• Read: Implement functionality for admins to view a list of all users, including details such as name, email, role, and account status.

User Interaction:

• Admins should be able to:
  • View a user list with sorting and filtering options based on attributes like role or status.

Implementation Notes:

• Use UserViewModel or create a new ViewModel for managing user operations in the admin section.
• Ensure that CRUD operations are in sync between the local database and Firebase.
• Integrate with FirebaseAuthDataSource for managing user authentication and deletion from Firebase.
• Utilize existing data models like UserEntity and UserRole for proper data mapping.
• Add test cases to verify that all CRUD functionalities work as expected.
• Ensure security measures are in place to prevent unauthorized access to user management operations.
