Focus chat input on manual interaction only

What does this MR do and why?

Focus chat input on manual interaction only

With the new panel design, the AI panel may be expanded on page load. In such case, we don't want the chat to steal the focus. However, we do want the chat to be automatically focused when the user manually opens the AI panel, or navigates between AI tabs.

How to set up and validate locally

1. On any given page, interact with the AI navigation rail.

• When the Current chat or New chat tabs become active, the chat input should get the focus automatically.

1. With the Current chat or New chat tab open, refresh the page.

• The previously opened tab should still be expanded, but the chat input should not have the focus.
