/**
 * Helpdesk domain detail page — read-only dashboard.
 *
 * Fetches customer, contract, handover, and related domain data
 * from a single async endpoint and renders all sections.
 *
 * All dynamic values are escaped via the esc() helper before insertion
 * into innerHTML. This matches the pattern used in helpdesk-detail.js
 * and other helpdesk JS modules in this codebase.
