Resolve a CVR company by CVR number

Resolve ONE CVR number (Det Centrale Virksomhedsregister) to the clean, re-joined company record: navn, lifecycle status, beliggenhedsadresse (with translated kommune/region names), virksomhedsform and hovedbranche. This is CVR register data; note that for personally-owned forms (e.g. Enkeltmandsvirksomhed) navn/beliggenhedsadresse may constitute the owner’s personal data — see docs/DPIA-CVR-SOLE-PROPRIETOR.md. Contact fields telefon/email are gated behind a source flag and suppressed for reklamebeskyttet companies (hjemmeside is not in the CVR model, so it is always null). Lookup by CVR number; company name search is a separate surface. A CEASED company is returned as it last stood (status inaktiv, ophoersdato set); 404 means the number never named a company.
