Show task status in UI

[mondaychen]

Sometimes it can take a while for

• page to load
• OpenAI API to respond
• more?

We have an existing component, but it's pretty simple and only visible in developer mode. It's nice to show this kind of information to users too. Maybe add icons too?
This component's location seems to conflict with the voice mode button. We need to resolve it.

We also need to add more types of status.

steps could be "understanding the page", "thinking", "performing action"

1. Overwrite the display string of "displayedStatus".
2. Display in non-dev mode as well
3. improve UI (move it to underneath the run task button) + add icon.
