Implement #5: each user gets to install applications from Flathub

As usual, NixOS provides an easy solution. Turns out we can create a user service for every user of the service with options under systemd.user.services.

The flakiness of the WiFi in the library complicated the matter a bit, but I solved it by making the service re-try every 30s if it fails. It seems to work fine.

As desired, whatever Guest installs is wiped out on reboot.

Currently guests can add other sources than flathub. I'm not sure how big of a problem this is.

Also, I don't yet have a solution for slow installation of first app. I guess the problem is mostly caused by slow network in the library. Installing something like Inkscape takes about 60 seconds, so maybe I'm just spoiled and it's not really that bad?
