Focus classic Duo chat input on user interaction only

What does this MR do and why?

Focus classic Duo chat input on user interaction only

In the new UI, we want to avoid the Duo classic chat input stealing the focus. The input now only gets the focos when the user explicitly toggles the chat panel.

1. Expand the Duo chat panel.

• The text input should be focused automatically.

2. Refresh the page.

• The AI panel should still be expanded, but the text input should not have the focus.
