Upgrading to Vue 3

[alienp4nda]

Working on transitioning the UI to Vue 3, state management to pinia, and to Vite instead of webpack.

Reason:
Vue 2 is EOL as of Dec 31, 2023
Pinia simplifies state management
Vite allows for less dependencies and less setup.

@AlfHou I'd like your feedback on this. I was able to get a somewhat functioning site within a day. The state management is a bit more involved.

That sounds like a great idea. I put in an effort to do the same a while ago, but I think ran into some issue and stopped working on it.
I don't have much experience with vite and pinia, but that sounds great. Feel free to create a draft PR if you want some early feedback :)
