Add and adjust @angular/pwa so ctrl app works offline and as a local PWA

[gerotakke]

This adds Angulars service worker/PWA implementation so that the Ctrl app works offline.
I have used the white Inputlabs logo for the icons because that was the one that was available in the highest resolution. I think it should be the green one though.
I needed to bump some versions in package.json to install it.
As I wrote in Discord:

The only downside I could find is that new versions are fetched at the mercy of their ngsw-worker — it worked very reliably for me but I couldn't quite pinpoint the exact time when it happens. So for “regular users”, a reload or clearing the cache doesn't reliably fetch the newest version, but a reload after a couple of seconds on the site should usually work. A real version number in the lower left corner would really come in handy here 😉
What reliably works is an incognito window though, and for local dev serving, the service worker is disabled anyway.

Thanks for the PR.

Here there is a 2000px PNG logo, I cannot export easily in SVG because the animation thingies.

I will review the PR properly in a few days.
