invites
use table-sm and no form-check-input so profile menu looks normal on
bs4. Profile was being read after being marked as used on invites, so
single-use invites were deleted and no profile was applied.
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
