Add desktop app

[zaknesler]

So, first off, this is a definite maybe.

My original intention was to make this a desktop app using Tauri, and this project actually began as a demo of Tauri and a way for me to get introduced to Solid.js. However after some consideration, I really liked the simplicity of a binary file that hosts the API and the frontend within the same process and port, without having to open a desktop app. You just host it on a server and can access it anywhere just a regular website. God it's just so nice.

However I understand that it would be cool to have it as a desktop app with Tauri. So I would like to explore adding a Tauri app. Hopefully, we can literally just have it run the UI and use the same API, so we don't have to extract all of our Axum routes to a service that must be used with Axum and with Tauri handlers.

Edit: Actually don't bother with Tauri! Just use Tauri's component crates:

• wry
• tao
• tray icon

It should be easy enough to render the webpage rendered by Axum, just handle window and system tray.
