Issues with Frontend Home Page and Backend Resource Logging

The description displayed in the circular graph on the home page contains incorrect information that could mislead users. Currently, there is no log entry when a resource is added to the system, which makes it difficult to track changes and identify who added the resource.

• Frontend Issue - Incorrect Description in Circular Graph on Home Page
• Backend Issue - Logging Resource Additions；
• Ensure that the user name is unique when registering
