Use websocket chat api endpoint to communicate from web app

- Use websocket library to handle setup, reconnection from web app
Use react-use-websocket library to handle websocket connection and
reconnection logic. Previously connection wasn't re-established on
disconnects.

- Send interrupt messages with ws to update research, operator trajectory

Previously we were using the abort and send new POST /api/chat
mechanism.

But now we can use the websocket's bi-directional messaging capability
to send users messages in the middle of a research, operator run.

This change should
1. Allow for a faster, more interactive interruption to shift the
research direction without breaking the conversation flow. As
previously we were using the DB to communicate interrupts across
workers, this would take time and feel sluggish on the UX.

2. Be a more robust interrupt mechanism that'll work in multi worker
setups. As same worker is interacted with to send interrupt messages
instead of potentially new worker receiving the POST /api/chat with
the interrupt user message.

On the server we're using an asyncio Queue to pass messages down from
websocket api to researcher via event generator. This can be extended
to pass to other iterative agents like operator.
