/**
 * Property-Based Tests: Ivanti Queue Remediation — Vendor Validation

 * Feature: ivanti-queue-remediation

 *
 * For any non-empty string of 1–200 characters (trimmed, with at least one
 * non-whitespace character), submitting it as the vendor field with workflow_type
 * "Remediate" to the queue API SHALL be accepted; and for any empty,
 * whitespace-only, or >200 character vendor string, the request SHALL be
 * rejected with a 400 status.
 *
 * **Validates: Requirements 1.2, 1.3**
