Permanently delete a conversation (owner/admin only)
Irreversibly removes the conversation and all associated data — its messages, followers, links, dispositions and custom-field values. This is distinct from Archive, which is a reversible soft-delete that keeps the thread for compliance and can be restored. Owner/admin only — a developer / viewer / billing seat gets 403 INSUFFICIENT_PERMISSIONS. Returns 204 on success, 404 on a missing conversation id in this tenant.
