New Logs Panel: Copy displayed fields

Copy log line in the kebab menu will copy the raw log line, which might be unexpected to users that are not visualizing the raw log line. <img width="261" height="241" alt="Image" src="https://github.com/user-attachments/assets/5ea95fd8-a997-4796-82bc-2b2e3c049f5a" /> Maybe we should add another option to the menu if the displayed text is not the same as the log line?
