Permissions System

A simple access control system was implemented so that no user can perform any operation unless they have the required permission, such as:

• ▫️ Viewing client list
• ▫️ Adding new clients
• ▫️ Deleting and updating clients
• ▫️ Performing transactions
• ▫️ Managing users

Before executing any operation, the system checks the user’s permissions to prevent unauthorized access.
