Users should be able to install the app on their computers

There are several methods for getting Questlists on the desktop. Here they are, in the order of easiest to hardest to implement.

1. Web SPA - we already have this, but we need to make sure the app can be installed by every browser. We should make sure the prerequisites are met, and let the browser automatically ask the user to install. See https://web.dev/customize-install/ on how to let it happen or how to do it ourselves.
2. Use electron. This is really really easy to do, however, electron is really heavyweight and is an extra browser instance, so I'm not certain we want a desktop app that's so heavy. If we do this, we need to make sure our signup process works and we can connect properly to firebase. We also need to decide if we want a local database only for desktop apps.
3. Use Tauri (https://tauri.studio/en/) for a lighter-weight desktop app. (is there another alternative?) We can use the firebase emulator as a local database, as we can package extra binaries. I tried a simple run with Tauri, and it worked well, but the icons didn't show up, so we need to address that issue.
