Add 41 frontend helper unit tests (app.js, nodes.js, hop-resolver.js)
Test pure functions from frontend JS files using vm.createContext sandbox: - timeAgo: null/undefined handling, seconds/minutes/hours/days formatting - escapeHtml: XSS chars, null input, type coercion - routeTypeName/payloadTypeName: known types + unknown fallback - truncate: short/long/null strings - getStatusTooltip: role-specific threshold messages - getStatusInfo: active/stale status for repeaters and companions - renderNodeBadges: HTML output contains role badge - sortNodes: returns sorted array - HopResolver: init/ready, single/ambiguous/unknown prefix resolution, geo disambiguation with origin anchor, IATA regional filtering Note: c8 coverage doesn't track vm.runInContext-evaluated code, so these don't improve the c8 coverage numbers. The tests still validate correctness of frontend logic in CI.
