/**
 * GET /api/chat/eligible → { eligible: boolean }
 *
 * Server-authoritative answer to "may THIS user use staff chat?" — checks the
 * DB (IsSystemUser + IsChatEnabled + non-limited role) via the shared gate, so
 * the client no longer depends on the possibly-stale logship_user cookie copy
 * of IsChatEnabled. A colleague who gets chat enabled in iDempiere AFTER their
 * last login therefore becomes eligible WITHOUT re-logging-in.
 *
 * Always returns 200 (eligible:false when chat is disabled or the user isn't
 * allowed) so the client fetch never throws / logs noise for ordinary denials.
