/**
 * Tests for #1020 — PSK channel UX:
 *   - Optional label stored alongside key in localStorage
 *   - removeKey clears both key and label
 *   - channels.js form has an optional label input
 *   - User-added rows render with a distinct badge marker in the DOM
 *   - Status feedback reports decrypt count from result (not DOM scrape)
 *
 * Runs in Node.js via vm.createContext to simulate the browser.
