List conversations for the WhatsApp account identified by phone_number_id. Default order: newest-active first by last_message_at (NULLS LAST). With updated_since, order switches to updated_at DESC so assignment/status changes are not buried. Supports short-lived server-side caching, and ETag/If-None-Match for unchanged responses.
