Convert ui ESM modules & svelte components into Typescript

[btakita]

I was able to successfully compile the hApp & get the ui client to run. However, I'm not able to see the port 8889 client to see commits from the port 8888 client (& vice versa) until a reconnect occurs.

In following the ui code, I see & am working on an opportunity to convert the Svelte & ESM modules into Typescript, to enhance my understanding. If there is not already an effort to do so, I'd like to refactor the Svelte & ESM modules to Typescript for my own understanding of how the UI & the hApp work. I already made some good progress & I'll submit a Pull Request soon.
