feat: assistant virtual list

[pixelass]

Motivation

adds virtual scrolling to prevent laggy scrolling on chats with long history

Known issues:

• Will always scroll to bottom when generationg. I could not find a way to implement the threshold of 200px
• Not a native scroll, therefore has several a11y issues (no keyboard scroll)

closing. Might revisit when we run into performance issues of long chats. This solution has too many drawbacks to be justified.
