Skatteetaten VAT register (MVA-manntall)

VAT (MVA) registration status per org number — an authoritative KYB attribute from Skatteetaten's register.

The MVA register is Skatteetaten's authoritative register of Norwegian businesses registered in the VAT register (Merverdiavgiftsregisteret). The connector provides the KYB attribute `mva.registered` + snapshotDate per org number, and — when the CSV extract file is mounted — also the registration date, any deletion date and category (Ordinary/Joint/Voluntary). A live fallback via Brreg `registrertIMvaregisteret` provides immediate value without credentials. Without configured sources the connector returns a structured 503 not_configured. Issue #1954.
