Alternative for non-ivy lib ngx-web-storage

[tillkuhn]

Feature
We currently use ngx-web-storage which doesn't seem to be actively maintained, has only 1 github star, and could be problematic when angular removes ngcc with v16 as there's a warning which claims that it's a non-ivy lib (see also angular/angular-cli#24797). Either use localstorage w/o 3rd party libs (seems to be easy enough, see refs), or use another lib
