Highlight the summarize messages from an LLM differently in the dashboard

[jhrozek]

This was the original title, changing to reflect the discussion:

LLMs send a request on user behalf asking to summarize the conversation so that it can display a title in the history. These are recorded in the database and it's mildly confusing. We might consider not recording them.

We should highlight the summarize messages differently (and maybe other messages that the code assistant sends) to show the user what the coding assistant is doing on its own.

I think recording them increases the user awareness that copilot is running them under the hood. Maybe we can keep them and mark/highlight them separately.

That's a good idea!
