Ability to close conversations via the API

We’d like the ability to programmatically close conversations using the Front API.

Right now, the API allows updating a conversation’s status to archived, but there’s no way to mark it as closed. This creates a challenge for teams like ours who rely on conversation IDs to track new vs. returning inquiries.

When conversations remain open (or only archived), any customer reply reopens the same conversation thread. This makes it difficult to identify new leads or inquiries programmatically and affects our reporting and workflows.

Requested behavior:

• Add an API endpoint or parameter that allows updating a conversation’s status to closed.

• Optionally, allow retrieving conversation closure info (e.g., closed_at, closed_by).
