Add pause/resume functionality (and button)

[rbren]

What problem or use case are you trying to solve? I want to be able to pause the agent so it stops its work, then resume when I'm ready

Describe the UX of the solution you'd like On the backend, a websocket action for pause, and another for resume

On the frontend, a button that sends those requests, and reflects current state

Do you have thoughts on the technical implementation? This will probably be a little difficult on the backend...there's weird concurrency stuff to consider.
