Fix lint failures, console.* convention violations, and CI Node version mismatch

- Add docs/capacitor-native-app-plan.md to hex-lint ignore list (code examples
  naturally reference hex colors in Capacitor config)
- Replace direct console.error/console.log calls with logger utility in
  historyView.js, profileCache.js, EventDetailsModal.js, ZapInterface.js,
  and notificationController.js
- Update CI workflow from Node 20 to Node 22 to match package.json engines
