/**
 * PR6 — documents hub `eoi_queue` tab.
 *
 * Verifies that:
 * - `listDocuments` with tab='eoi_queue' returns only EOI docs in
 *   draft/sent/partially_signed status
 * - `getHubTabCounts` reports the correct eoi_queue count
 * - Other doc types (NDA, contract, welcome_letter) are excluded
 * - Completed/expired EOIs are excluded (those belong to other tabs)
