Add "Copy" function to copy all log content to clipboard on UI

[bounlu]

Description

It would be great to add a button to copy all the contents of the log on the UI Dag Logs screen to clipboard. Currently there is only download button but it adds extra step through a temporary file.

Use case/motivation

It's often desired to copy paste the log to AI tools for debugging and this simple button can speed up things.
