[Enhancement]: Add copy button to every assistant chat message

[ashrafchowdury]

Description

Currently, the copy button is only available for the last assistant message in the chat. This enhancement proposes adding a copy button to every assistant message, allowing users to easily copy any message from the assistant regardless of its position.

Additionally, enhancing the visibility of the copy message button would be beneficial, as it is currently difficult to see that such a button is available.

Benefits:

• Users can easily copy any assistant response regardless of its position, enhancing usability and efficiency, especially in long conversations.
