rewrite* most web ui code in typescript

i wanted to split up the web ui components into multiple files, and
figured it'd be a good chance to try out typescript. run make typescript
to compile everything in ts/ and put it in data/static/.

This is less of a rewrite and more of a refactoring, most of it still
works the same but bits have been cleaned up too.

Remaining javascript found in setup.js and form.html

package-lock.json
