Update code to use vite and typescript

[C-Loftus]

Currently this repo uses js and vue cli. This is fine, but makes it harder to catch errors and some of the vue tooling is now a bit outdated. The package.json is a bit hard to append to now that some of the older dependencies aren't the recommended option anymore

I believe it would significantly improve developer efficiency to use typescript in the project and use vite. This is the standard recommended setup for new vue projects.

A Potential Plan

I would be happy to submit a PR for the changes described:

• I would start off by only porting the existing code to typescript and vite
• I would not add any new dependencies beyond those required for build

After that is merged, then future PRs could be done to make things more idiomatic / add new behavior. However, wanted to keep the start pretty simple.
I don't envision this would be too long to accomplish.

Along the way, I think it would make sense to add a pre-commit config so there is a consistent style across the codebase and no eslint errors
