Extracted pure utility functions (esc, sanitize, formatBytes, formatTime) into web/ui/util.js with CommonJS export for Node testing compatibility. Added 19 tests across 4 suites using node:test + node:assert (zero deps). - util.js: browser-compatible utility functions - util.test.js: 19 tests (5 esc, 3 sanitize, 6 formatBytes, 5 formatTime) - package.json: 'test' script → node --test util.test.js - mise.toml: js-test task - app.js: removed duplicate helper functions (now in util.js) - index.html: load util.js before app.js
