acp: Fix issue with claude code /logout command (#37452 )

### First issue In the scenario where you have an API key configured in Zed and you run `/logout`, clicking on `Use Anthropic API Key` would show `Method not implemented`. This happened because we were only intercepting the `Use Anthropic API Key` click if the provider was NOT authenticated, which would not be the case when the user has an API key set. ### Second issue When clicking on `Reset API Key` the modal would be dismissed even though you picked no Authentication Method (which means you still would be unauthenticated) --- This PR fixes both of these issues Release Notes: - N/A
Add onboarding banner for claude code support (#37443 )

 We plan to set aside time each week to pair program with contributors on promising pull requests in Zed. This will be an experiment. We tend to prefer pairing over async code review on our team, and we'd like to see how well it works in an open source setting. If we're finding it difficult to get on the same page with async review, we may ask you to pair with us if you're open to it. The closer a contribution is to the goals outlined in our roadmap, the more likely we'll be to spend time pairing on it.
