/**
 * One-off import of historical "Website – Contact Form Submissions" from NocoDB
 * into the CRM `website_submissions` table, so they show up in the Inquiries
 * workbench alongside post-cutover submissions.
 *
 * The cutover migration imported interests / residential / berths / expenses but
 * NOT the contact-form table — those general contact-page inquiries (the
 * "broker"/"investor"/"owner" enquiries) were left behind in NocoDB.
 *
 * Idempotent: each row maps to a deterministic `submission_id`
 * (`nocodb-cf-<id>`) guarded by the unique index, plus a `migration_source_links`
 * ledger row (`source_system='nocodb_website_submissions'`). Re-running is a
 * no-op for already-imported rows.
 *
 * Usage:
 *   pnpm tsx scripts/import-website-inquiries-from-nocodb.ts                # dry-run
 *   pnpm tsx scripts/import-website-inquiries-from-nocodb.ts --apply        # write
 *   pnpm tsx scripts/import-website-inquiries-from-nocodb.ts --apply --port-slug port-nimara
 *
 * Requires NOCODB_URL + NOCODB_TOKEN in env (same as the migration). Writes to
 * whatever DATABASE_URL points at — point it at prod ONLY with explicit approval.
