Fix Port Errors

If you encounter port conflicts, ensure that all instances use the same port number.

Files to Update:

1. src/main/java/com/computer_security_project/client/ui/ChatUI.java
2. src/main/java/com/computer_security_project/server/ChatServer.java

Modify the SERVER_PORT to the same value in all files:

private static final int SERVER_PORT = 5050;  // Ensure this matches in all files
