[v2] Missing meta tag in head to allow fullscreen webapp on iOS

[ibanezbass]

Adding a shortcut to home page allowed for the app to be launched full screen on v1. v2 is missing this feature.

As a work-around you could first save it to home-page with v1 and then launch the v2 server.

What tags do we need for this, anyway? I think in v1 they were all generated by webpack-pwa-manifest but we don't use that anymore.

I believe this is it:

<meta name="apple-mobile-web-app-capable" content="yes">

Thanks!
