feat(admin): ban user

[CUexter]

This feature request aims to implement the functionality for administrators to ban a user in the twitter clone app. The following functionalities need to be implemented:

UI

• In the user management page, administrators should be able to see a list of users and their current status (active or banned)
• Administrators should be able to ban or unban a user by clicking a button in the user management page

Server-side functionality:

• Store the ban status of a user in the database
• Check the ban status of a user before allowing them to post tweets or perform other actions
• Store and retrieve the ban status of a user when displaying the user information

Remarks

• Only administrators should be able to access the user management page and ban a user
