OpenViking is multi-tenant and requires X-OpenViking-Account and X-OpenViking-User headers. Without them, API calls like POST /api/v1/search/find fail on authenticated servers. Add both headers to _VikingClient._headers(), read from env vars OPENVIKING_ACCOUNT (default: root) and OPENVIKING_USER (default: default). All instantiation sites inherit the fix automatically.
