Import a state registry (operator)

Upserts registry rows for a state (1-5000 per call) and records a registry_syncs row. Gated by NOTARY_ADMIN_EMAILS — 403 for everyone else. Existing rows refresh registry facts only; claimed profiles keep their edited fields. registryAddress is stored for claim verification and never rendered.
