add qr code to insights->about->tor

[Reckless-Satoshi]

This PR adds a QR scan button to Insights -> About -> Tor onion property.

Scanning the QR codes is very handy for the apps. However, I did not find where to scan the main startos entrypoint QR.

This PR is not tested, I have no experience with Angular/Ionic and just edited code without setting up a dev environment . Hopefully it is not far from working.

Need a few changes to get it working but works great once fixed!

Suggested change

	import { ToastController } from '@ionic/angular'
	import { ModalController, ToastController } from '@ionic/angular'

I cannot comment on the direct line, but you also need to add the following to the class constructor:

private readonly modalCtrl: ModalController,

so its finalized form should look like:

  constructor(
    private readonly toastCtrl: ToastController,
    private readonly modalCtrl: ModalController,
    private readonly patch: PatchDB<DataModel>,
    private readonly config: ConfigService,
  ) {}
