Draft: Bot UI

WIP – NOT YET IMPLEMENTED

Description

Adds bot page with chat ui

• Add page with chat
• Implement getting old messages by root message id
• Implement getting a list of chats
• Make typescript types
• ? Move from reflux store to react hooks or something else. I think this will make the chat ui little more independent and easier to develop
