Issue a 전자세금계산서 in one step (`registIssue` = 즉시발행) — `invoicer_corp_name`, `invoicer_ceo_name`, `invoicee_corp_name` (+ `invoicee_corp_num` for 사업자 buyers), `items` (`item_name`, `qty`, `unit_cost` KRW/NET), `tax_type` (과세/영세/면세), `purpose_type` (영수/청구) in; **mgt_key + ntsConfirmNum** out. The seller 사업자번호 comes from the header; **부가세 is computed for you**. `mgt_key` auto-generated if omitted.

Look up one invoice by `mgt_key` + `mgt_key_type` (SELL default / BUY / TRUSTEE) — returns the `stateCode` (200 발행완료, 300 국세청 전송대기, 320 국세청 전송완료, 330 전송실패, 400 발행취소), `ntsConfirmNum`, timestamps and totals.

**Force immediate** 국세청 (NTS) transmission of an already-issued invoice. Normally transmission is automatic the **next day** (익일전송); this only sends it now instead of waiting for the batch.
